Hello all, I have problems to translate some field names on Opigno private messages. "Subject" and "Select the users you want to send a message to" parts on send new message and "View" on message preview can not translate on user interface translation https://ibb.co/x7GkFWD , https://ibb.co/4TjKygy. Do you have another suggestion about it?
