Popped because marathon split in parts going as individual difficulties is not how it should be. Marathon maps are exactly: marathons.
Before you point at Armin's mapset: yes, it did happen in the past, but only once (edit: unless there are approvals I am unaware of). Please, remove all the diffs from the set except "DROP THE BASS"; you can keep its name.
If you need separate difficulties for each song so bad, you can map each song individually and submit it as a proper mapset. Merging songs into compilation and then splitting them again by having individual difficulties does not make any sense. This is not only my decision, but I also asked peppy directly.
