NavigationQueryFilter Ignored sometimes

I am using detour crowd and NavQueryFilter with NavArea classes.

For some reason sometimes (like 50% of the times) the pathfinder is ignoring my navquerryfilters completely.

E.G. My AI is pathing through the Excluded area (Note: Besides Excluding I also set the maximum cost + entering cost for the area) and as far as my brain can understand → my AI should avoid this area…

But My AI which is using this filter is traveling in water area (well sometimes it also stuck there forever).

What to do ?

Also what are these flags ? there is 0 documentation about…

Fisabling detour solves this problem - but disables detour…

Will this Engine ever fix its navigation bugfest ?
