How to change a Field name


I am brand new to Sysaid and need some help. Above entry fields in incident tickets there are labels like "Title", "Description", etc. See attached for an example.

I figured out editing the Translation file can change these labels, however it only changes the label for NEW tickets and does not replace the label on existing tickets.

Example: I change the "Title" label to "Problem Description". When I open new tickets they contain my changes. Exisiting tickets still contain "Title" as the field name.

How do I change "Title" to "Problem Description" so it reflects across all existing and future incident tickets?
