Problem with the translation of the search attribute

Hello ,
The problem is the following :
I created 2 attributes that are with the Greek title and i use them in the “Search tour” bar.. I used WPML to translate them in english , but the translation dose not appear in the english “Search tour” bar menu. Instead the words that appear are in Greek. I used WPML and searched with the taxonomy translation and also with the WPML string translation.I also used Loco translate to translate some texts , but i don’t think that i ever changed the attribues names throught loco translate Any thoughts why this happens?
