External Links with custom Icons

I am using a couple of external Apps in the NC Menu/ Top Iconbar.
Before Update to 10.0.3 integrity check said everything is okay. But now it is complaining about Extra Files in the apps / external / img folder

How to ged rid of this annoying message optional: how to use different icons than the globe icon?

Install Update and

Move the folder in


I’m sorry for my bad English

this doesn’t fix the annoying message of extra files…
