If one has a file where all of the expected tabs:
don’t show up:

If you select and edit the toolpath in question:
and choose “Select Current Vectors”
and go to the Design pane:
then Edit Tabs:
We see that only the tab which shows up is associated with this geometry, and if we then add tabs where desired:
