Hello Anil,
Please note that compatibility mode puts Internet Explorer in a state that can cause such behaviors. If you want to use other version than the installed one, you should use a native Internet Explorer version as the compatibility modes are not supported and have some unexpected behaviors.
You can see the supported browsers at:

Please let me know if you need any additional assistance.
