Lover Girl doesn´t appear on search list

[Lover]

Hi Tom,

if I click on my lovers-list, a girl who is my lover appears with status yellow (in room). I f I make a search she doesn´t appear. How is it possible?
If I search for her and just enter the name she isn´t known. If I choose "also offline" she appears. But only if I just enter her name; if I click anything other (e.g. female) she´s not there.
Today she bought a 3-days-membership. Is it depending on this? She even has no blue star.
