Conflict "Indent" in Rough and Finish part in Lathe

Hi
I'm working with a wood lathe CNC machine that is operated by GrblGru V4.2.0.
I've imported Candlestick.dxf and I want to lathe a specific part of it.
I've tried to use "indent left" in the Rough and Finish setting But some weird action happened,
when I do type -100 in indent left in "Rough", the value in "Finish" MUST Be a lower value.
-78 was the last number that seems accepted by GrblGru.

Why?!

First of all, thanks for your feedback. :)

Please install the new version V4.3 once. I have changed a lot in lathe mode lately and uploaded only in beta versions.
I just tried again the indentation -100 in roughing and finishing cycle and it looks good.
Please let me know if it doesn't work for you.
