Custom Venue preset data!!! A Question

Okay this is not a question to help fix the issue as I have a good idea what happened, but more of a technical question and I hope this is the best place to ask.

sometimes I reset my Sims 4 Documents folder for a clean slate...which means I delete most of the folder except the important ones (tray, save, etc.). I opened one of my lots that had a custom venue preset with everything setup. But once in, I noticed that the preset was completely gone! 

I think because of deleting the sims 4 doc. folder I got rid of some information. so my question is if anyone knows where the data of the custom venue presets are stored?? did me deleting the sims 4 documents folder get rid of them?? or is it stored somewhere entirely different??

that way I can avoid messing up again.
