Well this is a weird situation… the tool shows that both your Sidebar and ToggleOpen are visible, and ToggleClose is hidden, which makes no sense given the blueprint logic and video. And it doesn’t seem to show any duplicate widgets or other weirdness.
Here’s a weird checklist:
- Is there any other logic in your widget BP that might be affecting this?
- If you click on the Open button in the designer, look at details, and switch on Modified Only (on the cog icon) do you see any unusual changes from the defaults?
- Could you temporarily hide or delete the Open button in the designer and check the behavior? Is there anything showing in game with the button deleted? If not, maybe recreating the button fixes the issue.
