WAD file location: WAD not found

Hi, I use DE 1.15.3 on Windows 7 and Windows 10. I try to load Doom WADs from a folder other than data/jdoom, the program just doesn't seem to find them. I set the new WAD location in Snowberry (doom settings), tried to set the IWAD folder in the UI, did a new install, removed the "Doomsday Frontend" folder. It didn't work.

What happens in Win10: Doom(2) loads, but I'm unable to select an episode. This part of the game menu is empty. The UI gives a warning: "No episodes are defined". In Win7, the game selection screen shows saying "no playable games were found". Selecting the IWAD folder with the "select IWAD folder" button doesn't work either. Did I miss something?
