[Plugin: Gravity Forms – Update Post] Not storing all data

It doesn’t seem to be storing all the information, for example, the email is stored, but the confirmation isn’t, also the first name & surname (two text fields) aren’t stored.

My form is a combination of normal fields, taxonomies & custom fields, but it doesn’t seem to be doing this on anything specific, as some of each work on the form with the info remembered.
