Formatting Problems in IE Compatibility Mode and IE8

On our site: http://millcreekmetro.wpengine.com/, (hosted on WPengine) we are noticing a lot of formatting issues in IE compatibility mode as well as IE8.

A few things we noticed in particular:
–
– Our social icons in our header do not display
-The four columns underneath “Explore. Experience. Enjoy.” becomes three columns with fourth column stacking underneath.
– The two columns underneath the four columns, also become stacked.
– The images in the recent posts on the homepage also were not being resized down appropriately (although I can’t seem to replicate this today!)
– The Mega Menu is stacking vertically instead of horizontally. (Under Visit and About Us)

I’m sure there are other styling issues I have not discovered. I searched the forums and saw the one post about making the change in avia.js as a temporary fix, but I tried that and it didn’t seem to change anything for me.

Please help! Any advice? Are more IE8 / compatibility view fixes coming soon? I saw your note about releasing more IE fixes soon, but not sure if that already happened in latest release. I am using 2.3.2.

Thanks!
