Hey Enzo, sorry for the delay in responding, I had spent some time trying to look back for the patches to this issue which are published in the thread; however, the simplest solution at the moment is to download and place the files from github found at:
https://github.com/mc12345678/EasyPopulate-4.0
I spent some time cleaning up some code last night to try to post a corrected version to the ZC site; however, what is there is functional and corrects the unfortunate issue that you have also come across as well as a few other things.
