Hi Uwe,

you are right. It is best not to share category options between categories
inside the same category combo. It is a problem with the current design. I
am aware of it and we will try to get it fixed. It has implications on
several aspects so might not be fixed this week. For now it's better to not
reuse options inside the same combo.

regards,

Lars
