I have localized pretty much all of the customer facing

I have localized pretty much all of the customer facing strings in Marketpress using POEDIT. However, there is a handfull of strings, which is not displayed in the localized language, despite the fact, that they are translated.
Below are the strings in question, which all related to lines are 240 in the marketpress.php:
- Please enter your shipping information in the form below to proceed with your order.
- You are almost done! Please do a final review of your order to make sure everything is correct then click the "Confirm Payment" button.
Thank you for your order! We appreciate your business, and please come back often to check out our new products.
- If you have any questions about your order please do not hesitate to contact us

It would be great if you could advise me on how to localize these remaining strings. I would be happy to share my de_DE.po files with you as well if that helps.

thanks!
