This might be a compatibility issue with the Instructor Role plugin. This plugin is unknown to us and was never tested by our compatibility team.
We need to replicate this issue on a fresh WordPress installation. Then I'll be able to escalate it to our compatibility team. For this, I created a test website with a clean WordPress install. You can access it through this link:

With this link, you'll be directly logged in.
Could you please install the LearnDash and add-on plugins and see if the issue is replicable on a clean WordPress installation?
I already configured WPML to have Estonian as the default language and English and Russian as the second languages.
Please also ensure you install the latest version of the plugin.
Please let us know when everything is finished and you can replicate the problem.
Important! Do not import your site to the test site. We must replicate the problem on a fresh, clean WordPress installation.
I just rechecked this ticket and can see that we replied around the same time. I missed your reply. My suggestion was to replicate the issue on the sandbox site. Your reply makes it unclear to me if you still need help with this issue or have found the solution. If you need further help, please replicate the issue on the sandbox site.
