Welcome to the WPML support forum. Before assigning your ticket to one of my colleagues, please allow me to guide you through some initial debugging steps to help speed up the support process.
Please note that the *Hybrid Composer* plugin is not included on the WPML official compatibility list for the Plugins - https://wpml.org/plugin/. It does not mean that this plugin is not compatible with WPML, but our compatibility team has not tested it yet.
Most probably you have to add WPML language configuration for the Hybrid Composer elements to translate it using WPML Translation Editor. Refer to the following documentation for more details.
