Pro Tools 12.7.1 issues with Space 11.2.2

[Sadie Tango]

I recently updated from PT 12.4 to 12.7.1. I'm using Space 11.2.2. Since the update, twice I've opened a session and the the dry/wet mix in Space has reverted to all wet, no dry. I didn't have that problem during the brief time I was using 12.7. Is this a known bug? It's kind of unnerving to have to reset reverb parameters that I've fine tuned already. So far it's happened on both the two recent sessions I'm working on.
