Youtube – Uploaded video on YouTube does not appear on the channel

According to threads in the YouTube's help forums, the copyright strikes are permanent and are not removed without filing a counter-notification".

Excerpt from the page:

If you believe your content was misidentified as infringing, 
you may file a counter-notification. If you did not have all
of the rights to post the material at issue, you MUST NOT 
submit a counter-notification. 

Good luck!

The feed is, well your feed. It displays basically your activity. If you like a video it will appear in that feed saying you liked xyz video.

If you don't want the feed to be the default option that appears you can go into the settings when on your video channels page and check Enable featured tab*. This will make a featured video appear and videos uploaded appear below (of course only public ones).
