Why does Slingshot add small straight lines (G1) when making (small) circles? And why going back and forth (G2 + G3) instead of choosing one direction?

In my project I have multiple holes of diam. 10 mm. While looking at the G-code I see two strange things:

1. Slingshot adds a few straight lines (G1) to the circles (G2 and G3). For what reason? Has this something to do with the tabs?

2. Why is Slingshot combining G2 and G3 code?
Some holes are purely done in one direction (see below) while others are done “back and forth” (see above)… Why?

This one is done “unidirectional” (same project!) but - again - with some “straight lines” added:

Hi Koenraad, thank you very much for your report, we are already at work to solve the problem.
