Sort issue, double portfolio items & remove "Read More/View Project"

Hi! Couple questions.

1. My sorting is not working. It will sort correctly for a moment, but them the page jumps to “Sorry, not posts matched your criteria.”

2. My portfolio items are showing up twice but I have [nimble-portfolio] only once on the page.

3. I’d like to remove the Read More and View Project buttons. I have the circles set to navigate to the Read More page and I don’t want any other navigation available.

Here’s like link to my site–in–progress: http://jonathanstephanoff.com/pilotingpaperairplanes/ldstephanoff/home/design/

Thanks!
