Problem with attachments which broke swap btn in GARNIN

I’ve run into an issue in MSFS 2024.

I’m trying to use prebuilt instruments from the MSFS 2024 library, as described here:

I’m attempting to add the Garmin 530. It appears in the model, but the SWAP (STB-ACIVE frq) buttons do not work—neither on my instrument nor on the one connected to the aircraft.

This is video:

However, if I remove the connected Garmin from the model, the SWAP function starts working correctly.

again video:

I’ve spent a lot of time on this and can’t figure out why this is happening. I’d like to use the library instruments, but they clearly aren’t working correctly.

Any idead ? Thanks
