plasma-pa widget doesn't show active port selector sometimes on Kubuntu 20.04

Sometime plasma-pa widget doesn't show the port selector for sinks and sources, even though in the settings I am still able to select the port. See attached screenshot. What I noticed is that if I start the system when headphones a plugged in, then the selector appears.

Please tell me if I need to raise the bug in the upstream, I can do that as well.
