Game icon doesen't update if anything is encrypted

I was trying to figure out why my game icon wasn’t changing and why it was always the default UE4 logo. I tried packaging without encrypting anything and it changed. Am I the only one with this issue, is it normal or is anyone else having this problem? I’m on Windows 10 Home 64 bits (1609) with Unreal Engine 4.21.2.
