Two Panel Tabs groups on one page not working.

I've got two regions on one page that each have their own group of tabbed content. Attached are a few images showing the problem as things are clicked.

001.png: This is what it looks like on load, this is correct
002.png: Clicking back and forth between the left panel works properly.
003.png: Clicking the "Featured Events" tab on the right tab causes that regions information to take over the "Search" regions tabs. The right region content is completley moved to the left and "disappears" Note that both tabs show up with the "Featured Event" tab (with broken "can't delete" view) below the Memorial view.
004.png: Clicking back to "Featured Memorial" on the newly moved content works as it should. But, in the left region where it shouldn't be.
005.png: Clicking back to "Featured Event" once more brings up both tab views but also doesn't highlight the tab with the intended purple background image.

I'm kind of lost as to how this can be fixed. I've tried setting the regions with and without CSS ID/Class names. I've made a test panel with two regions and dummy content comprising of two tabs per region and that works fine. I'm wondering if it might be the content within those tabs that is causing the problem... I'll have to experiment more.

Thanks for any input you can provide!
