Can't ride dragons

[BufusTurbo]

Hi folks, I'm aving an issue with Dragonborn DLC's shout "Bend Will".
I've unlocked all words and got through the necessary quests, but when I use that shout on a dragon, it goes to the ground, says something like "shall we fly?" but I can't actually ride the giant lizard: no options appear when I aim at the dragon.

I have installed the Unofficial Legendary Patch (but it solved nothing), and have no mods altering dragons.

 

can someone help me?

If you have MFG Console, when you click the dragon in console does it come up with any base changes?

[BufusTurbo]

It says the last base change is from the Unofficial Patch itself.
