Gamepad-Friendly UMG ~ Control Cursor with Gamepad Analog Stick! Easily Click Buttons!

Hey , thanks for this plugin, it saved us quite some time. The plugin is working well, both in the Edtor and in the shipped game. However, when packaging the game I get the following error messages:

This is new since I copied the whole plugin folder “GamepadUMGPlugin” from the ZIP file into the Plugins folder of my project.
Any ideas how to get rid of these warnings?

Thanks, and cheers!
