Couldn't display SAP Icons in Fiori Launchpad in IE

Hello All,

We are migrating from SAP NetWeaver Portal 7.01 to Portal 7.40 SP12. We are using Fiori launch Pad as entry point to portals. When Fiori Launchpad is displayed in Internet Explorer(IE11), We couldn't see SAP Icons for Options, Search, Show Groups, Personalize Homepage, Tile Catalog, Back actions (Please find in the attachment). We couldn't see SAP UI5 Icons in tiles too in IE. We could be able to see all of them fine in Chrome and Firefox.

Could you please suggest if you had similar issue or any inputs to solve the issue is appreciated.

Thanks,

Sudheer.
