This has happened with some other plugins. Somehow there’s a migration that created the table but the migration system doesn’t recognize that it ran.
I don’t know how to do it well enough to explain it to anyone. In broad strokes, You’d stop the restore before it migrates (there’s a switch for the restore command to do that) and drop the table, I think. If that makes sense, or almost makes sense you might be able to figure it out with help from https://ask.discourse.com/
If that doesn’t help and you’re in a hurry and have a budget, you can ask in Marketplace or email me. If you’re not in a hurry, or don’t have a budget, there’s a chance that someone can explain what to do in a way that you’d understand.
