same issue like me https://github.com/SoftFever/OrcaSlicer/issues/5706
I think it's a problem with the "extra perimeters on overhangs" setting
same issue like me #5706
agreed
Been dealing with this same issue for the past 2 weeks.
Is there an existing issue for this problem?

How to reproduce
Create model with areas that are to be bridged.
Actual results
Sometimes areas that are designed to be bridged get overhang wall treatment, and filled with a concentric layer. This increases the chance of failure. In many cases a symmetrical stl will have bridge assigned to one feature, and overhang wall assigned to it's mirrored twin, for no apparent reason. In some cases this seemed to be accompanied by 'floating cantilever' warnings.
Expected results
Probably bridging should always take precedence, and maybe query the user about what treatment to give otherwise. Orca really needs a way to zoom on a specific area to display what some of its warnings are talking about.

Anything else?
The log/project zip is not useful for demonstrating the seemingly random selection of overhang or bridge, as the first few times I noticed this all I did was take screenshots, and didnt save any 3mf.
Below: The 3mf infcuded here is merely to demonstrate what I believe is the cause of the issue. ie: if 'detect overhang walls' is on then it may interfere with things that are intended to be bridged.
Below: instances of mesh being sliced with a different treatment to otherwise identical overhangs, both intended to be bridged.
Below: 'bridge counterbore holes' with sacrificial layer failing 1/4 of the time, despite all 4 holes being essentially identical, and the left and right section of stl literally being mirrored. I was also seeing some interaction with 'detect overhang walls' here too.
