Tinker Board S R2.527 Equalizer plugin broken

After installing the “Volumio Simple Equalizer” plugin on the above mentioned configuration, sound output is broken.
There is a configuration issue: After activating the plugin, I am unable to select the correct DAC model, as it always jumps back to the wrong “HiFiBerry Amp” instead of “HiFiBerry DAC”.

I consider this plugin to be broken.

To be fair, I never had this kind of issue.
