And here it is after I re-opened the project:

Note the changed LFO sync values (1s vs 0.1s)
I'm using Reaper 4.54 and the latest Diva version. The same occurs when the plugin is moved/copied from one track to another. Somehow it doesn't persist its state correctly.
And e.g. Polysynth/HS Vocal Clav is one semitone off (low) when recalled - Transpose is -13 instead of -12 (which has been mentioned before, but here's a specific preset).
