Audio effect issues - Afwtdn [filter avfilter.afwtdn ] Unexpected return format

Hello there,

I started using audio effects in kdenlive and discovered the following error:
Afwtdn [filter avfilter.afwtdn ] Unexpected return format.
This error is shown inside the window of the audioeffect.

I searched for ways to solve this but didnt find any solution. I tried different kdenlive versions and also the 24 beta. the error happens on every tried version. Any ideas how to solve this?

I have the feeling that it might have to do with a missing default value for the interface? Please help. I need those effects. I am getting the error for several effects. How can I solve this?
