Having issues with KISSlicer understanding my geometry of the modes

Do we have any slicers options in Canvas for P3P other than Slic3r and KISSlicer? I’m having issues where there is a printed strange geometry in the middle of my print where there should be infill only. I have to replicate this print 20 times so I’m looking to figure out this issue to increase presentation and performance. I also want to note that the actual print nozzle path is different than nozzle path of Canvas Preview for this random geometry as it doesn’t show up in the preview.

I’ve had fantastic experience with Cura outside of Canvas. I keep hearing other Palette users using other slicers. How are they using other slicers?
