Massive List of Macros, RollTables, and Decks suddenly appeared - how to get rid of them

Hey Folks, Within the last 36 hours, a massive list of what appears to be "standardized" macros, decks and rolltables suddenly appeared in my game - and I have no idea why or what I did. Anyone have any thoughts on a way to... mass remove them? Clearly I must of done SOMETHING, since they seem to appear to be things like Random Name Generators, Background Generators, ect. Thanks!

Hmm. Sounds like the result of a particular plugin or possibly a script. You could bulk delete them with a Mod script. If you want to PM me a join link and GM me, I might be able to help with that tomorrow. 

So... I'm 99% certain it happened when I installed the Xanathar's Guide Plug-In without realizing exactly what it was... It popped up on the Games page and I got confused, because I had already turned Xanathar's Guide on in the Compendium sharing section of the game configuration, and without realizing what I was doing I thought I had somehow turned THAT off, and told it to install the plug-in thinking that would reenable it for my players... Sigh... I REALLY wish when you uninstalled a Plug-In it would also remove all the crap the Plug In brought with it.
