Especially once they effed up the first time; you'd expect them to be more careful going forward.
Care may not have much to do with it.
HR probably needs to know employees' legal names. But their software may not have a place to store an alias, preferred name, or nickname.
Moreover, Personally Identifiable Information (PII), like names, addresses, phone numbers, and such, is typically data that HR is required to keep secure. Keeping a separate list of preferred names as a separate spreadsheet on someone's computer is not generally an option, as it is a basis for a lawsuit if it gets out.
The result is, even after the first flub, they may not have had any means to fix it in the short term.
