Performance, capability and functionality in CA Configuration Automation (CCA) is limited when using Internet Explorer (any version) due to the JavaScript engine used.   
Microsoft Internet Explorer uses Chakra writren in JScript  (32bit) as the engine, which has under performed in any benchmarks.  Microsoft raised Microsoft Edge (part of Windows 10) that uses a fork of JScript  in pure JavaScript still calling it Chakra (with support for ECMAScript 5.1).   With those changes, Microsoft Edge performs to or above Chrome and Firefox when viewing CCA UI
If you are using Windows 10, please use Chrome, Firefox or Edge, not Internet Explorer for reasons stated above.  Any other version of an operating system, please stick with Chrome or Firefox
