HALion Sonic not allowing "audition" of presets

Just a small niggle but I’m finding that when you single click on a sound in HS SE Library (from within Cubase 12) the “try before you use” feature isn’t working any more. It no longer lets you play around with a sample before you choose to create a track with it. However, it is working OK with Flux, Trip and Verve.

Any suggestions?
