Cubase 15 not saving multiple Arturia Keylab MK3 programs (sounds) after closing project

Hi, I’m using Cubase 15 Pro with my Arturia Keylab MK3 (pro). When working on a project, I can open multiple sounds from the V lab collection and work with them on separate tracks, but after I close the song and open it again, all the Keylab MK3 sounds default to the same sound as the Classic Jun Keys, as shown on the Keylab screen.

Am I missing something in the way I need to save the project, or is it a problem with Arturia’s software? Anyone else experiencing this?

Best Regards
