Filament doesn't retract for some travel movements using PrusaSlicer The printer does not retract the filament for some travel moves result in scrape printing part as shown in picture.

This is my printer setting. Not sure which part be the problem.

I want my printer to retract the filament as I have set it to. Where to check and what could be the problem?
Minimum Travel after Retraction is exactly what it says on the tin: if the travel after a retraction would be less than 2 mm, it does not retract. You'll want that to be short, but not 0, because retraction can lead to under extrusion at the start of a new line, and every swap from one shell to the next shell right next to it is classed as travel.
