xAPI quiz score reporting problems in Docebo LMS

Hello all,
I've built a simple 8-question quiz in Storyline 360. Multiple Choice and T/F, each question worth 1 point.  When I publish via xAPI and upload the quiz to ScormCloud, everything reports as expected.  In Docebo, though, there's some weird conflating of points and percentage, so if I get 8 out of 8 right, instead of giving me 100%, it's telling me I've gotten 100 out of 8 correct, and reports a percent total of 1250%. 
I'm working with Docebo tech support to figure it out, but they've pushed back that it's an issue in the content, not the LMS, and suggested I change the point values to 12.5 per question (which I can't do in Storyline since it won't allow a partial value, which in and of itself is a weird shortcoming).  I disagree with their take on it, as we have a use case that means we only want any individual quiz question to be worth 1 point.  If nessa I can explain that in more detail.  I feel like there's something going on in how Docebo is grabbing the point and percent variables from Storyline upon quiz submission, but I'm still trying to prove it.

Has anyone else run into something like this? Any thoughts would be helpful.
