Compile errors when adding new C++ class

[lotsofbugs]

Hello. When I add a new C++ class, empty or not, to my game (that's using UINav) I get compile errors related to this plugin. These are the errors:

2>C:/Program Files/Epic Games/UE_4.21/Engine/Plugins/Marketplace/UINavigation/Source/UINavigation/Public/UINavInputBox.h(44) : LogCompile: Error: An explicit Category specifier is required for any property exposed to the editor or Blueprints in an Engine module. 2>C:/Program Files/Epic Games/UE_4.21/Engine/Plugins/Marketplace/UINavigation/Source/UINavigation/Public/UINavInputBox.h(49) : LogCompile: Error: An explicit Category specifier is required for any property exposed to the editor or Blueprints in an Engine module. 2>C:/Program Files/Epic Games/UE_4.21/Engine/Plugins/Marketplace/UINavigation/Source/UINavigation/Public/UINavInputBox.h(51) : LogCompile: Error: An explicit Category specifier is required for any property exposed to the editor or Blueprints in an Engine module. 2>C:/Program Files/Epic Games/UE_4.21/Engine/Plugins/Marketplace/UINavigation/Source/UINavigation/Public/UINavInputBox.h(53) : LogCompile: Error: An explicit Category specifier is required for any property exposed to the editor or Blueprints in an Engine module. 2>C:/Program Files/Epic Games/UE_4.21/Engine/Plugins/Marketplace/UINavigation/Source/UINavigation/Public/UINavInputBox.h(56) : LogCompile: Error: An explicit Category specifier is required for any property exposed to the editor or Blueprints in an Engine module. 2>C:/Program Files/Epic Games/UE_4.21/Engine/Plugins/Marketplace/UINavigation/Source/UINavigation/Public/UINavInputBox.h(59) : LogCompile: Error: An explicit Category specifier is required for any property exposed to the editor or Blueprints in an Engine module. 2>C:/Program Files/Epic Games/UE_4.21/Engine/Plugins/Marketplace/UINavigation/Source/UINavigation/Public/UINavInputComponent.h(20) : LogCompile: Error: An explicit Category specifier is required for any property exposed to the editor or Blueprints in an Engine module.

Even an empty C++ class returns this error when compiling. If I delete the newly added C++ classes, I get no more errors and I'm able to compile. I'm using UE4.21

Hi lotsofbugs (pertinent username ;) ),

I have already fixed those issues on the latest release of the plugin. Have you updated it from the Epic Games Launcher?
