Cut through issue when using tabs

When cutting out parts on our Thermwood 43 CNC router, I have noticed an issue with using tabs. Typically, when toolpathing a model, I will do an outline cut, leaving a 1/16" skin so all parts remain fixtured. After the initial outline, I then clean up any tight radius parts with a smaller tool, then come back and do my final cut. The final cut is all done with one toolpath, using tabs only on small parts. I specify a cut through of -.004, and have consistently noticed that on the small parts that i place tabs on, there is no cut through. It will bump up for the tab, but still leaves a fair amount of skin, maybe 1/32" or so. The rest of the model cuts through with very light grooving of the spoil board. This appears to be a bug in CAM. I have attached the CNC file below.
