CAPsMAN 2.4 & 5 GHz same SSID

Hello there,
I recently moved from Unifi to Mikrotiks Audience and run the Wifi via CAPsMAN.
What is a bit weird to me is, if setup just SSIDs with authentication (like for a home AP) I receive any SSID at 2.4 & 5 GHz.

As soon as I create a dedicated channel setting and use it for my SSIDs, I only get 2.4 GHz.
Even though I already copied each configuration to the channels and put the new configuration to the provisioning tab.

Any ideas what I am doing wrong?
