Hi Alejandro,
It seems that you are using a third-party plugin for that and you need to contact the third party plugin developer to get an answer.
You can test by changing our theme to another theme and see if the problem persists this shows it is not related to our theme code.
The other point is that you use the Plugin Loader Filter which might cause the issue as you might misconfigure the loading of the plugin in question.
Please kindly test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
Thank you for your understanding.
