If you're playing with a mod that uses entire planet definitions instead of surface definitions (which is rather odd) then you can add them to the blacklist manually in the mod startup settings.
I'd rather not hardcode a bunch of exceptions for mods incorrectly using the planets system like this.
For Factorissimo it looks like you'll want to add to the blacklist:
factory-travel-surface
nauvis-factory-floor
vulcanus-factory-floor
And all the other planet names + -factory-floor
I might be wrong or missing something else, so you'll want to take a peek at any other planet definitions they add.
