Br442 Talent 2 Uncoupling

I found a problem today. I cannot uncouple 2 units of BR442. It works just fine in TSW2020 and I can't make it in TSW2? Can some good person confirm it's not only my problem?

 

I can’t uncouple anything in koln Aachen, neither Ice or talent

 

I just wanted to give this post a bump as I still cannot uncouple either train, as well as the dopple stock sets except where they meet the locomotive.
