Android app auto upload and sincronization folder

I make some tests today using android app to synchronize a folder between smartphone and my nextcloud server.

the problem occurred according to the scenario:

  1. I set an android folder to auto upload and all files uploaded to server;
  2. inside all files, if I choose sync options in folder all files are downloaded to the NC default folder, duplicating the files.

this is normal or a bug?

is the correct upload folder shown in your android app when you go to setup folders?
