X-axis skipping?

Offset fill requires a lot of movement in both axes which will be prone to positional errors especially if the rotary is the roller type.

Standard fill should give you better results with “Fill all Shapes at once”.

Temporarily reducing ‘Y Acceleration (mm/sec^2)’ by half or even more (Edit > Machine Settings) will help prevent part slippage on roller rotaries, although it does look like your part is slipping in X which is unusual…wipe the rollers clean with a damp cloth and ensure that the rotary is positioned perfectly parallel to the X-axis.
