Translation of RSVP form feilds

Hi,

I am trying to update the translations for the RSVP form in Norwegian.
I have followed directions here: https://theeventscalendar.com/knowledgebase/k/how-to-override-plugin-language-files/

It has worked great for the text eg. “Please submit your RSVP information, including the total number of guests and RSVP Here.”
However I can’t find the strings to edit the form fields eg. “Name” and “Number of Guests” as well as button “Finish”. I also tried with a Find and Replace plugin but the changes won’t stick to the second page / form perhaps Ajax?

Is there another .po file I should be using? Or a trick for finding form fields in the event-tickets-nb_NO.po file?

The currently the form came half translated on install, so it looks very strange.

Any help would be greatly appreciated ??
