UMG Combobox clones Options

I’m attaching and detaching the Widget dynamically to the Viewport. Every time it’s attached it clones the available Options of each Combobox.


  • Create a Widget containing a Combobox with some Options
  • Add Widget to Viewport
  • Check the available Combobox Options
  • Remove Widget from Parent
  • Add Widget to Viewport
  • Check the available Combobox Options (any Combobox Option should appear twice)
