Multiple VeraLites, GC-100 app, keeps reappearing when deleted

[PJJP]

I have 4 veralites. One is the master that can see everything from the others. Each of them have the "Global Cache GC100" app. I deleted it from everyone unit except the master, but it keeps reappearing. The problem is that the master already sees all of the GC100's I have, and when a slave unit sees one too, it then shows up on the master unit again, cluttering my space and causing problems.

How can I make this stop and get rid of it once and for all on the slave units?

This could be a problem with the "Auto detect devices on my home network" setting on the slave veras. I am disabling now to see if that fixes it.
