Appointments+: Next Month untranslatable with .pot file

Hello,I'm transalting Appointments+ in French and i can not translate correctly the button "Next Month".
I do not find "Next Month" In the .pot file. I can translate each word individualy but in French, those words are not in the same order.

In French we say "Mois suivant" ==> "Month Next".

You should have an entry in the .pot file for "Next Month" and not for indivial words in the same sentence.

Hope you can correct that in your future release.
