X3 Backplot not representing actual cutter patch correctly but posts OK

[BTCS]

I noticed an unusual event today in back plotting a simple contour tool patch.

 

I was comping onto a contour and stepping it down in the z axis ( 1 move only) and pulling comp off at the end, or final depth of the contour.

 

Done this a Million Times.... switched for lead in and out are all set correctly.... but when I backplot it and step the path through the kidney shaped contour, for some unknown reason... the path on the final move approaching my end point in the geometry becomes a linear move in the backplot... and show similar in Verify..... However after the path runs to completion the view of the toolpath refreshes and looks as it should, and posts correctly without the linear move I saw in backplot step.

 

Is this a bug?

Do you have tool compensation set on control?

yes..... and again... shows up correctly at regen... just not stepping thru
