I am experiencing something very weird happening with the callout heads on my project. They all seem to be pulling themselves into central collection points at various random spots throughout my floor plans. Originally I assumed that it was one of the planners collecting their heads for quick reference purposes or something along those lines but after speaking with the people responsible for these callouts they say Revit is doing this on its own. I've tried some quick exercises to try to replicate this but have been unsuccessful so far.
Here is some info about this project to help with the trouble shooting process:
1. This is a work sharing project with multiple users working on the project
2. We use scope boxes to control views
3. we use a central model for printing and the responsible parties can't remember if these views were copied from the level model into the central model or vice versa
4. This issue has not happened yet in the central model where these callout were probably manually positioned at some point

Below is an example of one of worst cases, 30 heads but they can collect in spots with as little as 2 heads

Hopefully someone has seen this happen before.
