It's because of Issei's extreme fascination to breasts that started all of it in the first place.

If it wasn't for him, Odin wouldn't have had the idea to give a nickname to Albion too. And because of that nickname, their pride as the possessors of DD, which they hold extremely high, was "smeared" (can't find the right word/group of words)
