Help please: CC Eyes Only Appear When I Randomise Eyes

I have this problem sometimes. I have many CC eyes, all are non-default. But sometimes, only a few will appear until I chose a different eyeshape. This is very annoying when I need to change the eyes colour but not the shape. I had an hybrid get eyes I usually only use for aliens as there is a shine painted in them that would give a normal sim a crazy look, so I went to change her eyes but only got those eyes as an option. And I have at least 3 kinds of cc Alien eyes, so it cant be bc of that.
