Bug trying to add or modify year line (SOLVED) [Resolvido]

When I try to modify or add a year line to a coin page, this message is shown:

Is only me?

Have you entered the catalog or just the number as it states in the error message?

Catalog | Number

Blabla# | 123

Catalog | Number

Blabla# | 123

I entered everything: the catalog code, the number, and some information in the comments line.

I'd been entering Aureo catalog numbers without any problems for about two hours, and then suddenly I started getting this error.

Fixed. There was a line much further down with a number but no KM name. 

Thanks and sorry, you can mark it as solved.
