You can improve the translations in the language files in /easyreservations/languages with the free program poedit.
If you just want to change one particular string my way is to open the .po file with any text editor and search for and edit the string. After saving open it with poedit, make a change somewhere, undo it and save again.
I’ll look into the creation of the resources, I thought that I have fully tested it.
