Ling_Gao Hello!  There are a couple of ways to open a site in IE mode.  First is using group policy (What is Internet Explorer mode? | Microsoft Docs) and the second is reloading individual sites in IE mode manually (Settings and more (the ellipses icon ...) > Reload in Internet Explorer mode). 

 

When using policy you can select the site to load in specific document modes.

 

When manually selecting "Reload in Internet Explorer mode" under settings, I have seen it will say "Compatibility Mode: IE(Unknown)" but just for a short amount of time as the page is loading and then it changes to "Compatibility Mode: IE11"  Is this the scenario you are experiencing?
