PWA Icons disappear in Action Sheet when app updated

Hi I have an Ionic Angular PWA App. We use action sheets with Icons. What happens is when we run an update of the app using SwUpdate and then app updates. However when we try open certain pages with Action sheets that use Ionic Icons those actions items don’t show up. The user has to close the app and the reopen. Then they appear again. Because of this behaviour I think it is do to with Lazy Loading. Any ideas why this might occur and the fix to it?
eg Is there a way to not lazy load specific icons?
