CTRL+TAB / Document switching in Corel 2021?

Hello,

do you know how to switch between documents with the new Corel 2021?

I have been using CTRL+TAB for years but now the switch happens in a difference sequence between the documents, or within the Object layer that ist currently activated.

This ist really annoying.

Sorry, I am not a professional graphic designer :)

Cheers!
