We'd like to help. Recommendations are based on a variety of factors. Have you tried removing recommended content by selecting "Not interested", as this will influence how YouTube suggests videos to you in the future. Hope this clarifies.
Thanks for confirming. To help the right team better investigate, can you send a feedback report from the device/account having the issue? Steps here: https://yt.be/help/feedback . You may not get a response but this'll help us identify issues.
