Thanks for contacting WPML forums support. I'll be glad to help you today.
First of all, sorry for the late reply; it was due to a higher workload.
1) I tried to replicate the issue, but I couldn't. (Kindly check the attached screenshot)
Could you please check if the issue persists in a minimal environment by following these steps?
1- Deactivate all the plugins except WPML CMS.
2- Switch to a WordPress default theme like Twenty Twenty-one.
If the issue is gone, activate them one by one to see which one is causing an interaction issue.
❌ Please backup your database before performing the above test ❌
2) Could you please share your Debug information with me?
You can read a detailed explanation about it here. (http://wpml.org/faq/provide-debug-information-faster-support)
The debug info will give me much information about how your site is configured.
I just checked and it turns out the WPML stuff is there twice on the page for me. 1 time correctly, 1 time incorrectly. I'll check what's causing this and let you know in the next days
