Program Change with Loopback Midi

Hello !! I’m French user (visit my YT Channel and follow if you like (https://www.youtube.com/channel/UC5wAq9NGyyozsqo11oqjS3g).
I make some tutorials about Digitakt but actually I have a problem.

With the latest update midi loopback with program change doesn’t work.
I use Track 16 with channel 16. I add a trig with program change lock but nothing. Not change.
I have change In the menu program change send et receive to 16 but nothing.

Is it an issue or I make a mistake ?
Thanks for you answer (and thanks for follow me on YT).
