Bend Will not working on any dragons

[gelgoog]

I only noticed this a while ago after when I encountered a dragon from the Diverse Dragon Collection mod that I want to ride. Take note that I rode other dragons added by that mod before this happened. I tried spawning vanilla dragons from the console (Blood-Elder) and it just displays the message "The dragon resists your voice". Loading back doesn't do the job either. Level 70 chara so there shouldn't be a problem regarding the levels. Even Ohdaviing resists it too.
