That's odd. What device is this happening on? Also, would you mind telling us some of the steps you've tried? We may have some more steps up our sleeve that you may not have tried yet. Let us know.
Thanks for the info. We'd recommend sending us a feedback report directly from your YouTube account with these steps: https://yt.be/help/RYwc . You may not get a direct response, but we do review everything to investigate and fix issues.
