I'm trying to add a specific name, ALICEA EDGARDO, into the unique values symbology. I type in the name as below:

But when I try to commit what I typed in by hitting enter (or tab) it throws in a semicolon, rendering it a value that does not exist in the data. Why is there a semicolon being add and how can I stop it? Is the add value window using some particular encoding?

This data is a half million or so polygons so I don't want to wait for it to automatically load nearly a million values just so I can break symbology for one single value.
