Translating Labels

Hi and thanks alot for this great Plugin!

I am currently aiming to translate our Shop and running against a wall on the RFQ labels. I read that there was an update to make it translation ready a while ago and also could find the strings in the WPML string translator, for example: RFQ Checkout- Choose the text for “Proceed To Submit Your Quote”

Still, when setting up the translation strings, the system wont use them but only what I have entered in the label options for both languages.

Can you help me out here?

Kind Regards
