Toolpath not generating correctly when tabs are activated in 2D contour

[btmarti1]

Hello.

I have been routinely using a 2D contour with ramp and tabs to finish the outside of parts.  On this particular part, I can't make it work.  If tabs are disabled, the ramp works correctly according to the inputs.  If I enable tabs, especially triangular tabs, the ramp toolpath goes totally off the rails, cuts air for a bunch of passes, then plunges right to final depth and cuts through where the tabs should be.  I have attached the .f3z file.  

Any help greatly appreciated !

Thanks

There are a couple high profile tickets logged with Tab right now. I've not looked at your file (yet), but I suspect it's the same issue

Yep, same issue. Rectangular tabs work, but I recognize that's a shoddy process..
