Translate some words

Hello,

Thanks very much for this plugin. It is amazing !

On my site, I use 2 languages :
– EN : https://perchoirenprovence.com/en/book-now
– FR : https://perchoirenprovence.com/reserver
(my wordpress is in French)

The translations are automatically and are good.
There are just 3 words that I do not know how to put them in English for the EN version.
They are the labels under the calendar (Disponinle – Réservé – En attente).

Thanks for your help
