Content Server not refreshing

I set up a content server and am having issues with it refreshing. So far I have it to be only local and it is not refreshing on either my pc or on my Nexus 7 using Moon+ Reader. On the pc I tried both IE and Firefox. I am checking Newest and tags to look for a newly added book. It does refresh if I stop and start the content server.

My pc is Win 7 and I am using calibe 0.9.11
