Hotkey not working correctly on new patch

Hello Devs,
since the last patch the hotkeys are not working correctly.

My settings:
C for Stable
Alt + C for Siege Workshop

X for Archery Range
Alt + X for Castle

As soon as I click “C” in the building menu, it shows the siege workshop.
As soon as I click “Alt + C” in the building menu, it shows the siege workshop as well.

As soon as I click “X” in the building menu, it shows a castle.
As soon as I click “Alt + X” in the building menu, it shows the Castle as well.

Please fix this.

Greetings
Weizenesel
