Yes, it sounds like the WPML translation needs to be addressed to WPML support, but I think XStore has its hands in the issue also ๐
I am trying to translate a word in a second language (Germany) using the WPML plugin, but after choosing Germany in the Menu Structure, the primary menu got erased. The menu in both languages is completely erased.
I think the issue is related to the XStore theme because WordPress reports that the theme does not support Menus, which is very strange to me. Please see the attached images as a reference.
