Fill Frustration with CNC

I am trying to use Luban to CNC “fill” engrave individual letters into wood disks.
Somehow the tool path changes drastically from “on the path” to “fill” methods.
The “on the path” method Gcode produces a code to cut the entire letter “on the path”. This is working great.
However, when I select “fill” method, the Gcode produces a little tiny dot. I loose the entire letter. I have run the boundary on the CNC to verify in fact that the Gcode is just the little dot-that is all the CNC is trying to carve, is just the dot, not the letter.
Thanks in advance for any help.

Please see attached snippet.
