Hello,
1) I’ve created translation for Core plugin – http://prntscr.com/rbb9l2 Please edit the translation here – http://prntscr.com/rbbahz > http://prntscr.com/rbbamw http://prntscr.com/rbbatq
2) Go to Loco translate > Themes > XStore > Sync translation – https://www.8theme.com/documentation/xstore/theme-translation/translation-files-update/ Then you will be able to find and translate “Available”, “Sold”.
Regards
