Items in online collections not appearing without workarounds

I've been having this problem for awhile. I created a screencast that demonstrates the issue, but basically I am not seeing any items in my online library or collections unless I fiddle with the Library Settings options and refresh the page. This is true on both the Chrome and Firefox (version 17.0.1) browsers, for both my Zotero accounts, and on different computers. The screencast can be found at http://www.youtube.com/watch?v=nncNNZHCdJc . Also, and this is important and I forgot it in the screencast - I am unable to click on an item and see its contents through my online library on Zotero.org.
