I see your headphone is without a microphone. So, the screenshot of mine is irrelevant. Sorry for confusion. In this case, the headphone microphone shouldn’t be displayed.
Reset audio settings to the original / default mode might be the next step. Please wait for more experienced helpers to come back. Thanks.
p.s) Did you try different audio profiles on your ‘digital microphone’? I never messed with the configuration files of PipeWire/WirePlumber.
