Mastery Pathways only opening up one option despite quiz score

[DPdesigner]

I am trying to set up a mastery pathway option for students in my course. It's self select, so there is a "quiz" where they pick which option they want to complete. Option A is worth 2 points, Option B is worth 1 point. I have the mastery path set to send the 100%-ers (anyone who chose Option A) to Pathway A and the 50%-ers (anyone who chose Option B) to Pathway B. But every time I test it, only Pathway A is opened up, no matter what option I select. I've tried changing the percentage numbers in the pathways set-up, but still no luck.

Any suggestions on what I might be doing wrong, ideas to try, etc. appreciate - thank you!
