This seemed to be happing quite often lately with homemade videos. Strange. No background radio or anything? I would contact support.
No problem. But you must solve this problem because you have 2 videos with a copyright and if another will take copyright too, you will risk to lose your channel. So just write to the support and solve the problem with this confusion. I know a member, MimiRabbit, she had the same problem and after speaking with the support, they took the copyright of her video.
As SloggerVlogger said, you should have left them up for now. Try resubmitting and if the same happens then contact firstname.lastname@example.org
I deleted them to try other videos, and unfortunately the same problem appeared, thanks to everyone who guided meAs SloggerVlogger said, you should have left them up for now. Try resubmitting and if the same happens then contact email@example.com
You mention all the footage was recorded by you ? This seems to be generally the reason this issue has happened lately, some have been "stealing" footage which is not allowed of course. Make sure to let us know the outcome. Good luck.
