Glitchy Rise completion

Hi, everyone!

I'm having an issue which I cannot seem to solve, and I was wondering if anyone has come across this.

I have a Rise course comprised of 14 lessons and 2 quizzes in two separate sections. The navigation is restricted, so I shouldn't be able to advance without having completed all previous content. Testing the course in ScormCloud, I come across this issue:

Navigating lessons 1-6, then a quiz, then lesson 7 (all which comprises the first section) works well. When I navigate the second section, say up to lesson 11, and I exit the course, once I re-open the course, I'm still in lesson 11 but it appears as though lessons 8 and 9 haven't even been opened.  So, lesson 8 has a 100% completion, lesson 9 has 0%, lesson 10 has 0%, but lesson 10 has 10% completion, and the only way to fix it is to go all the way back to lesson 8 and re-take lessons 9 and 10, even though I had already completed them.

I've tried numerous tests, such as deleting specific lessons, re-ordering them, and going so far as rebuilding the course in a new course, but nothing seems to work.

Any ideas?
