AVG Exceptions literally does nothing when I try to add

I've had AVG for many years and I could add exceptions just fine, this is important because for some reason (don't know when it started or why) now I can't add any exceptions, I can edit or remove but I cannot add exceptions. When i click the folder or file I want excluded, the AVG window either blinks away and back or freezes for a split second, and the path I wanted to make does not appear. There is no prompt, no error message, literally nothing happens. I searched the internet and I could not find anyone with the problem I have. I uninstalled, installed and restarted my PC when prompted. Now I've lost all my previous exceptions and I still can't make any new ones.

I have the AVG Zen free protection, does not tell me what year it from.

Hello Chris,
Let we first appreciate your valuable efforts which you have taken to fix it.  Since you have mentioned that you have reinstalled your AVG program to get the issue fixed, we keep you informed that once you have reinstalled your product, your added exception will be removed manually from AVG. We don't have the option to recover back,. once it has been reinstalled.
To get to know about whether you have installed the latest version  of AVG we would request you to check the product inbuilt version in AVG interface.
Thank you for understanding.
