[Résolu] I am trying to translate wpml string on wordpress site

Hello! I am trying to translate wpml string on wordpress site. String language is for example latvian. Russian translation works, but adding english translation won't apply. I have updated both wordpress and wpml to latest versions. When I tried to add english wpml string and translate it into latvian and russian, then russian translation worked, but latvian didn't apply. How can I fix this?
