First of all, based on the debug information you shared I find that you are using the outdated WPML plugins. We always recommend running your site with the latest stable plugin version.
*** Please make a FULL BACKUP of your database and website.***
After updating WPML plugins to latest stable release version, if your issue still persists:
- what if you switch to the parent theme and do you see it working as expected with the parent theme?
- Could you please try to resolve your issue by deactivating all third-party plugins as well as the default theme to check for any possible conflicts with any of the plugins or themes?
