Julie doesn’t have the ability to see all ghosts.  It’s specifically tied to her band, her boys.  Before Sunset Curve appeared in her studio, Julie had never had any sort of paranormal experience before  ;  she wasn’t sensitive, and didn’t even believe in ghosts.  The fact that she’s suddenly acquired a ghost band doesn’t mean she randomly developed the ability to see them all.  Julie can just see...  these particular ghosts.

Meaning!!  if Caleb Covington himself was doing a one - man meringue in the middle of her living room, Julie wouldn’t be able to see it  ( unless Caleb wanted her to ).   She can’t see all ghosts.

If a ghost is closely tied to the boys, however, she will slowly develop the ability to see them.  This only happens when another ghost means very much to the boys  ---  essentially, being a part of their souls.  I explained it here, in my fic recognition :

Julie's the only lifer who can see him — but that has less to do with Willie, and more Julie herself being a force of nature. Even she says Willie isn’t really there — not in the way the boys are, clear as day, so solid she can literally touch them. To Julie, Willie is an outline; a translucent shadow with faint features. Sometimes she can make out the details of his clothes, or the smile on his face… but most of the time, he’s too hazy even for that. His voice is faint and tinny, resounding from far away.

The only reason Julie can see him at all is because he’s so closely tied to Alex, and Alex is tied to her — like a working game of telephone.

“That’s got to be it, right?” Julie theorizes. “I don’t have the same bond with Willie as I do with you guys, so…”

“It’s like our souls are connected!” Reggie pipes up.

“Through music,” Luke adds. He and Reggie exchange wide eyed looks, and nod, like they’ve just said something very wise.

How Julie sees and interacts with these sorts of ghosts is explained here, from another one of my fics, still alive but i’m bearly breathing :

When they spot what looks like a skateboard zooming on its own through the empty art museum foyer... Flynn hammers on the museum's glass doors. The skateboard skids to a stop.

It takes a minute of focus before Julie is able to see him — Willie. Or really, the outline of him, a poorly-rendered hologram with the vague definition of facial features and clothes. Willie is illuminated to Julie’s eyes, not through any connection with her soul, but whatever connection Alex has with his. Like a cosmic game of telephone. Julie can’t see what Alex sees as clearly as he’s able to… but Willie is still real for her. As he phases through the door to greet them, she's able to look him in the eye and smile.

“Hi, Willie! Great to see you again.”

“Uhh, yeah.” Even his voice is an echo. “Great to… see you too? Still super weird to be seen by a lifer, but — uhh. Why do you have a bear dressed like Freddie Mercury? And why does he look so miserable?”

“It’s Alex,” Julie says. “Alex has turned into a teddy bear.”

You get the picture?  She can’t see these ghosts the way she can see the boys, and definitely can’t touch them or make them visible.  The magic connection she has with the boys could hypothetically extend to another ghost like Willie, but only if the ghost was very close with the boys, and developed a close relationship with Julie herself.

basically :   Julie can’t see all ghosts, only her ghosts...  but if her ghosts love another ghost, she will be able to see them, and they could eventually become one of her ghosts too.
