Why do deleted Content Browser folders reappear?

Hello everyone,

I cleaned up post a bit due to an excessive number of answers, and wanted to provide an official update on this issue. This issue is currently in our system, UE-11796. It is being investigated by our developers; however, there is currently no timeline for when a fix will be released. Their efforts are currently heavily focused on high-priority crash and showstopper bugs. I will continue to provide updates regarding this issue as they become available.

Have a great day
