1) Some translations were marked as Fuzzy https://prnt.sc/z94krc
2) Some translations are just missing
3) You did not create the translation for the XStore core plugin https://prnt.sc/z94frj I created translation. So, translate the necessary strings, for example https://prnt.sc/z95d63
4) Edit sidebar widgets static block to change content https://prnt.sc/z954os and sidebar widget https://prnt.sc/z959rm
I checked translations and it works if you translate texts.
