unwanted layers keep reappearing

[Anonymous]

Here's my problem, somehow a project has gotten littered with all sorts of layers from consultants. I have gone through all drawings in all hotlinked modules, I have turned all tools to "one active layer, and have successfully purged all of these unwanted layers. Everything looks great, I run updates, everything looks great, but then I reopen that file the next day, and all those unwanted layers are back. I feel like a failure , I have checked all forums, and tried everything, can't clear 'em. Any suggestions.

Do you have attached XREFs?
Those can create attributes.
Also, do you have DWGs/DXFs placed as Drawings? You can check that in the Drawing Manager.
