Songs appear twice in Playlist on Apple Watch

I have a gym playlist downloaded on my Apple Watch. I noticed that the playlist has double the length it should actually have because every song appears exactly twice in the playlist. But it’s not like Song A, Song A, Song B, Song B but like Song A, Song B, …, Song Z, Song A, Song B, …, Song Z.

Does anybody else have this issue und maybe even know a solution? The same playlist appears normal on my iPhone, Mac und iPad.
