Cookie Banner not showing

Hi,

I have 2 copies of basically the same setup:
https://titz.tz-stadtschlaining.at/ and https://miksch.tz-stadtschlaining.at/

On the first page the Cookie Banner is not being displayed, on the second one it is.
I tried to go through the assistant and disabling all other plugins. This didn’t do the trick.

Could you please support me on this?
Thanks and BR
Thomas
