3 Kopeks, Y#128a (USSR) - some correction needed but it's locked

I couldn't make any corrections to the date listing as it is locked:
see the attached sceenshots

The following date variety currently listed by Numista seems to be a mistake: "1991 l", I've looked through a number of specialized USSR catalogs (I'm a native speaker of Russian) including the lates edition of Krause (38th ed.) and such a variety is not listed by none of them, so it seems to be an error and is to be deleted

Cheers, Alex

done thanks
