Borderlands The Pre-Sequel: Quest experience bug/glitch?

I have encountered an issue with the experience gain on the Pre-Sequel. For the past few days I’ve been trying to play the game with my friend (in which they’ve reset it several times) so that we could finish getting to level 70 faster. I have finished the campaign and all DLC for it, so I understand I will not get a quest reward item. But I do not understand why I am not getting the quest experience. When I would play Borderlands 2 and play on others’ campaign (on the same, Ultimate Vault Hunter mode) I would not get the quest reward item naturally but I would get the quest experience. The only XP gains I get in their game is NPC kills.

as far as i know, unless you too reset, you’ll get nothing for quests you’ve done already.
