I am translating shapely to a rtl language and already translated almost all parts of theme. The main POT file was for version 1.7 , so I made it compitible with the latest version (1.2.3) by getting help from other language packs and costimizing theme.
Here is the problem:
Some parts of theme insist on not being translated 
… Although I have addressed some of them from 2 or 3 different directories. I changed the codes based on version 1.1.2 and it worked! But I want it to work proper in version 1.2.3.
Here are the directories I used for the missing translations in the following screenshot I’ve sent as an example:
Welcome Screen Title:
#: inc/libraries/welcome-screen/class-epsilon-welcome-screen.php:427
msgid “Welcome to %1$s - v”
Welcome Screen Description:
#: inc/libraries/welcome-screen/class-epsilon-welcome-screen.php:433
msgid “%1$s is now installed and ready to use! Get ready to build something beautiful. We hope you enjoy it! We want to make sure you have the best experience using %1$s and that is why we gathered here all the necessary information for you. We hope you will enjoy using %1$s, as much as we enjoy creating great products.”
#: inc/libraries/welcome-screen/class-epsilon-welcome-screen.php:502
msgid “Getting Started”
#: inc/libraries/welcome-screen/class-epsilon-welcome-screen.php:508
msgid “Recommended Actions”
