YouTube is acting up :(

Hello, so I have been using this app for a bout a year now, and I loved every bit of it. however, when I installed the latest update it seemed to have made my YouTube act up, I don’t know if it’s just me or what but here

MI made this video as an example and when I tried to make another one this happened 

It worked but it got rid of the other example I just made, and even from my page it’s gone.

I don’t know if this is a bug or a glitch but can you please fix it? the blurred out ones are just pics of me making stupid faces and I really don’t want people to cringe at my attempt of a duck face, hah.
