Anybody else ever try to build up a custom table of manufacturer feeds and speeds for a "Tool Type" of "V-Bit Engraver"?

There is no default table and when I manually enter a table (or automatically generate a table via "Generate Sizes"), it never gets saved. If I click on "OK" to save and exit that screen and subsequently return, the table is deleted.

Similarly, if I try to save a tool utilizing the table, it is never recorded.

I watched a video regarding how to develop a custom table, followed the steps, but still no luck.

I am trying to enter information for an Amana V-Bit (30-degree with 0.010" Tip Width).

I also noticed that "Tool Type" of "Chamfer Mill" also has no default table.

It is as if angled tips can't use this feature? I wonder how custom tables work with diameters which fall within the tapered portion of a drill bit....

Sorry, I'm a noob when it comes to engraving. Maybe this question is not even valid. If somebody can explain what I'm missing it would be appreciated, however.
