Widget BluePrint's "UEFN Button Quiet" disallowed

[BoC_re]

I can use the loud and regular buttons, but I am having trouble with errors only on the quiet button.

=============================================

LogValkyrieValidation: Error: Found disallowed object type /FortUILibrary/UIKit/Buttons/MaterialInstances/CTAButtons/MI_UIKit_Button_QuietLight.MI_UIKit_Button_QuietLight, Referenced by:Content/UI/RestartUI.uasset, Plugin mount point:/ProjectA.
UEFNValidation: Error: Found disallowed object type
UEFNValidation: Error: /ProjectA/UI/RestartUI

=============================================

What do you mean it is disallowed?
Is there any way to improve it?
