Hello,
1. I do not see the problem http://prntscr.com/obmjug or https://prnt.sc/obmk0l > http://prntscr.com/obmk4r
Please clear cache and check one more time.
2. About “billing details” text, have you made changes in template files? Please do not edit files of the theme directly. Provide us with temporary FTP access, we will check why this text can’t be translated using Loco translate plugin.
3. http://prntscr.com/obmjh0
If you find more strings that can’t be translated, provide us with a list of these strings.
Regards
