Thank you very much for the proper details and the video, it really makes the support much easier.
So, the issue appeared because this option was activated: https://i.imgur.com/aS3afWG.png
I've already turned it off for you. The explanation is, that whenever that is activated, the plugin opens the search settings pop-up automatically. But since the search bar is not visible by default (and it's visibility is not detectable), it's placed to the last known location.
I believe you may have enabled that option by accident only, but now it should be okay, no more automatic pop-ups.
