[BUG][FLEXI] Issue checker doesn't show levels with same ID

[Gronkling]

When trying to build my nxp file, or use replay manager, flexi toolkit throws this error
"This pack has multiple levels with the same Level ID. Please fix this. The issue checker can tell you which levels have issues"

I look at issue checker, click "Error check", issue checker responds with "No issues identified"

Resetting ID on repeat levels, or one random level does not fix this problem.
