Trouble moving app to system

Hi everyone

Every time i'm moving an app to system, it just disappears (using lucky patcher). When I look the app up in es file explorer, I see it is in system but I can't interact with it. Also the app has the green andoid logo, not the logo from the app itself.
Does anyone know how to fix this?

Ps: I know I don't do anything wrong because it worked fine on my htc m8.

Thanks :)
