The parameter I use is not returning anything when I run the proc in the test by the package

I have a procedure that when I make the query in it I have the correct results. However, when I pass via parameters in the plsql Debug it does not consider the field in question.

The field is the same type as the table (varchar2) and the others work, not this one.
