Unfiltered banters are a general problem. But Wyll needs fixing in many areas. That second contract (good to know I am not the only one running into it, though, it can mean another response simply does not exist), that banters and his dancing scene. Just got it - completely out of the blue, with not a single flirting between the characters - and no, there is no way out of it. They fixed Gale's responses (somewhat, the neutral response now exists, but if you choose it, his animation and later talk to you are of harsh rejection) but with Wyll there is absolutely no even an imitation of a "friendly path" in this scene. Or a hint that you need to stop in the middle of a dance. Straight to the kiss you go.

I have a constant Jacob Taylor vibe from Mass Effect, where writers simply forgot that he was a romanceable character and there were a few people who did romance him and all but cut him out of the next game plus added a wife to him.
