Preset missing!? (chiptune arp)

[hacksmurf]

I worked on a project a few months ago that I'm very proud of and I used the Jupiter 8V's included preset "Chiptune Arp".
I opened the project today to improve the mix and I see that the instrument is using a completely different preset. I can't find the original preset I was using at all. My song is ruined unless I get back the original preset.
Either I accidentally deleted it (doubtful) or something else strange happened.

What the heck is going on?

I am using Arturia V Collection 3 with FL Studio.

OK I fixed the issue. The preset was not missing. But the Jupiter VST for some reason was set to the first indexed preset and I had to manually set it again. This also happened with another instance of Jupiter that I had in the project. Is this a known issue?
