Can't Extrude the number 7 when using SW txt

I am trying to use SWTXT in my part.

I am unable to extrude the number 7 itself because of too many contours. The 7 has an extra squiggle on the backside of the number (see attached).

I cannot edit the sketch for the number nor select the contour I want extruded.

How to I report this bug to Solidworks?
