Today I came across strange issue with object names translations. In our org we are using polish language as default.
SFDC translates Accounts by default as "Konto" :
But for our needs we had to rename it into "Klient". Basically renaming works perfectly in every place execept LEX Lead Conversion popup :
Seems like SFDC is still using default polish translation for Account. We did the same for the Opportunity and it also doesn't translate only on this lead conversion popup.
Any idea how to fix it?
