Autocomplete rule - National Identifier - NID type validation

Summary:

Hello,

In the use case for an autocomplete rule, It's mentioned that I need to build the rule on the person national identifier object. I've tried but I can't make it work properly because it always validates the last row (the current row).
I need the CUIL NID type to be mandatory and if a add a CUIL first and another one after it validates the last one and I can't continue, shows the error that I need to add a CUIL.

I tried changing the part where I get "Person National Identifier.Current row" but there is nothing else or I can't find it.
