In my error_log I found this notice: Deprecated: contextual_help is deprecated since version 3.3.0! Use get_current_screen()->add_help_tab(), get_current_screen()->remove_help_tab() instead. in /var/www/html/web/cms/wp-includes/functions.php on line 5088
This is triggered by line 345 in WPML_OptionsManager.php.
I have investigated the issue and it seems this file/code belongs to WP Mail Logging by MailPoet. It seems this isn't an issue related to our WPML plugin, in this case WPML means WP Mail Logging.
Nevertheless, I investigated the issue for you. I hope it helps.

I have found on plugins support forum this issue was already reported by users.
There hasn’t been an official update from the plugin author, but the fix in post 1 works.
This is related to WP Mail Logging, it only happens when the plugin is active.
WPML_OptionsManager.php uses the variable $contextual_help.
Line numbers 345, 396, 402 406 and 452 all have “contextual_help” in them. Replacing “contectual_help” with “wpmail_logging_contextual_help” fixes the error and the plugin seems to function as normal.
I would advise contacting plugin support to see if there was any official progress in fixing this issue.
Let me know if there is anything else I can do for you.
