Clips not Matching current filter setting

Here is the message that is popping up

No Clips match the current filter setting

To clear the filter setting, choose all clips from the filter pop-up menu above, and/or click the reset button in the search field in final cut pro x

I know it has to do with the proxy and optimization, but I have tried all that. I can't even import any clips.

Nothing to do with optimization/proxies. It's the browser search box in the upper right. Make sure it's cleared.

Thank you, I got to work now.

Another problem I am running into is that the files are losing quality in playback. I am using proxy settings cus I am on a macbook pro.

Proxy are low quality files. Do they need to be rendered in the timeline? You might want to try using high quality in playback preferences.
