Mark that I have banknote doesnt shown

I found one case that mark is not showing that I have specific banknote.

This I have, 5 leva banknote 1962

and when viewing swap offer from user lavv, I get this

showing that I DO NOT HAVE that banknote, 5 leva 1974, 

and sholud be that I have, but not same year.

Other markings are shown well.

Those are different banknotes on different pages. One is P#90 (1962 you have) and the other is P#95 (1974 you don't have).

N#202349 ← you have

N#202422 ← you don't have

Nothing wrong with Numista, you don't have that specific banknote.
