Replicated folders (shortcuts and Icons) on Binder

Hello! Binder is making multiple (and unnecessary) copies of the shortcuts of the folders and “manuscript” icons. When I try to delete them (IF the option is available), the original file is sended to the trash (that´s why I suposed ist´s just a shortcut and not a real copy). The atachedd image can explain it better. The selecteds in blue are the only folders I want to keep. Could anybody help me to understand what is happening? Thanks!

Note: just noticed that everytime I close the project and reopen it, it gets worse, with even more “copies”.

I found just now a topic that looks like a similar problem:
