The question would be, what show(s) were their songs from. The best way for teams to not get in this mess, with as loosy goosy requirements as this year has, is to file their bios timely, well before their first event, and list all the songs they are using, and the shows they came from. Most of the dance competitors at Lombardia did not do that. Bad move. HUGE! ...especially for teams wanting to stand out by using music from obscure or very recent shows.
Boney M has a musical

There is at least one Michael Jackson Jukebox musical...so One More Chance is probably OK too

They should have been fine, but it was their own fault. They did not file a timely, complete bio.
So while I am.sorry for them, I hope they have learned a lesson.
Both 'Daddy Cool' and 'Gotta Go Home' are in the songlist for Daddy Cool, so those choices are legal. Don't Stop Till You Get Enough has never been staged and the song list isn't known; I can't find evidence of 'One More Chance' being used in any other musical either, so it may be the problem. If it has been used in one that's actually been staged and is a legit musical, but their team didn't file the paperwork correctly including the names of the musicals, the deductions are their own fault - everyone was told they had to do it before the season even started - but it'll only be a one-time thing.
If somebody got the rules for seniors mixed up with the rules for juniors and thought the pattern could be set to something other than a musical in seniors too, though, that's a more serious failure on the part of choreographer and/or coach, and they're going to need a revamp. There might be something in the Daddy Cool songlist that works for the pattern in its place.
