I'm a bit confounded - I went in to look at this filly in the GMT lab:

Stormosaurus KP 3g

She's not hom KP (not eligible for the club), but both of her parents are het KP. In the GMT lab if you click on the alleles, it says "Your horse has the ? allele for this Kit Promoter gene.
Kit Promoter is an untestable gene. You will always see the option to modify on an untestable gene but will only be charged if that horse does not already have that gene. No edits are available for this gene" rather than the "change ? to ? for 1 GMT token."

Shouldn't changing one or both of the alleles be an option? She definitely missed a copy (or both). I'm not sure I want to change her specifically, just trying to figure out how this works.

Thanks!
