Deck Editor problem - quantity column not showing

I'm using Forge for MacOS 1.6.34.
While building some decks in the Deck Editor, in the Current Deck tab / List view, I used "Toggle to show/hide options for current view" to hide some columns I didn't need. At a certain point I noticed the Quantity column had disappeared from the view even if the corresponding checkbox was still ticked.
Now I'm no longer able to see how many of each card I have in my deck and I could not find a way to restore the missing column.
I also tried to Reset Editort Layout from the troubleshooting section in the Home tab, with no effect.
Am I missing something stupid here?
