Score possible in studio does not match with lms

Hello everyone, I have some issue, I have a Subsection (Not graded - Timed Exam), include 2 Unit
The first Unit has 1 problem with 3 questions, so 3 point possible (ungraded)
The second Unit has 1 problem with 1 question, so 1 point possible (ungraded)
Everything is fine in studio, but in lms, I realize that when I view in lms, it’s does not match
Here is my case

Expect is “1 point possible” in lms

Note: I export the course in staging env (which is having issue), then I import to my local, I can not understand why it correct and match together. Is it related to cache or not?
