Lost all the images in my notes

I’ve used restore once, but that was a long time ago (August 2019 Inkdrop on Windows randomly not shutting down correctly again last 2 versions - #9 by craftzdog ). I ended up loosing some data when doing this restore because I’m using the mobile version as well, and the changes in the mobile app had been overwritten. So I’ve never done any restore since.

The notes I gave in the exemple has been created after the restore, so it cannot be due to it.

How do I check this?

I did not delete the files myself, so how come they were deleted?
