I don't see the "OK" status for an extended period on any pin, neither Bookworm nor Bullseye.

There is something odd going on with this node though:

I see several such pins where the "radio button" in the config does not get saved / populated, eg pin 31/GPIO 6

In the pic below, these pins are marked with an asterisk comment.

The pins affected by this are the same for me on Bullseye and Bookworm
