[Ifeffit] Warning "e0 is greater than 10"

Hello Feff community, I am practicing on using Artemis to fit a UO2 XAFS data I measured. The parameters I used can be found from the pic attached. The Artemis project file is also attached. I have been getting this "e0 greater than 10" warning on many of my fittings. Will picking a slightly different E0 change the result much? Any suggestions on how to improve this fitting? Thanks!
