Problems with festivals

I added Provinssirock 1991 festival with incorrect date (ripped from incorrect wikipedia).
6.-7.6.1991 should have been 8.-9.6.1991.

Apologies for inconvenience.

Please combine these two overviews:

I can't figure out how to add this festival, because it was spread out over several venues in Shinjuku, Tokyo.

Ideally I wanted to edit a gig I listed to reflect that it happened as part of this festival but the lack of a concrete location and therefore how to create the festival is beyond me. It's not the end of the world if it can't be done, I was just going for maximum accuracy.

Not sure if anyone knows how to do this, or if it's even possible (I know you can't assign two different festivals to the same venue on the same day), but can you forcibly remove a setlist from a festival without changing that festival info?

This setlist was automatically added to the Montreux Jazz Festival Japan:

If you check the venue schedule from that day, the above concert took place at 19h00, and then the festival started at 23h30. These are completely separate events, and it feels very wrong to me to have a Jpop group included in a jazz festival.

This festival has his name as venue, please correct:
