Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
I guess upon rollover - she used to have 6m I know because her cub inherited White Hyena spots and I thought they are icky.

In all her cub inherited two markings that are hers. The stud does not have them in case there is doubt.

I do not keep markless lionesses in my collection. I am 100% sure she hat 6m because I kept her to pass on White Dorsal Line.
