Tuplet key commands [solved]

Hello, I updated my computer OS (to 64bit only) and was finally able to upgrade to Dorico version 5 on my desktop.
I am a bit confused and would need a little help with the key commands dealing with the tuplet input. Have there been any changes from version 4 to 5?
In my Dorico 4 installation I used ö for switching to triplets, whilst inputting music. To leave triplet input I would use shift-ö.
I had a third key command shift-; for inputting other tuplet values than triplets.
In my new Dorico 5 environment I re-assigned these key commands - but I can’t seem to be able to work as before. If I press ö I can’t continue with inputting triplets. I need to press enter additionally to confirm, before being able to input the triplets.
Is there a new setting I am not aware of?
Thanks for a little help.

After some further search I found the solution. I had previously hacked the .json file, see this thread (from 2020)…
