is it possible that search window is finding results even though the pet hasn't got searched gene researched?

I was searching puma with silent pace this way:

checked 'puma' in species category, then genetics, gene 1'silent pace', also checked 'both recessive and dominant' and 'all checked' below, and the results I've got is this pet:

he has only two genes researched and there's no silet pace there, is this a glitch or the search window is showing a pet that really has silent pace, although not researched? or am I doing something wrong?
