some small circles are not executet completely by a grbl plasma setup

hi folks,...
i have some wired behavior when i CAM little holes from an svg or dxf file.
the cam output in sheetcam looks fine, also the preview in bCNC looks ok.
but when i paste the gcode in https://nraynaud.github.io/webgcode/ or send it to the mashine (grbl) the problem is visible.
some circles going to be executed and others with exact the same size are not .... only the lead ins are made.
if i tweek the operation settings, lead in length for example, then some circle which where ok before are not ok and vice versa.
postprocessor: grbl plasma (only modifyed the M3 command a bit)
it happens with sheetcam tng dev 6.1.72 win10 and also with sheetcam tng dev 6.1.57 linux

any suggestions?
regards

generated gcode
