Prototype overlay background not reverting

Lunacy version: 11.1 Help → About (F1 or Fn+F1)
OS version: Windows 10

In my design, I have a hotspot which opens a overlay, and dims the background. In the overlay, I have 2 buttons, a cancel button that closes the overlay and a confirm button which navigates me to a different page.

When I click the cancel button and close the overlay, the background dimming reverts to normal. Whereas when I click the confirm button, the prototype navigates to the correct page, but the background dim remains. I have to click on the screen again for the dimming to be removed.

Anyone have an idea if this is resolvable as yet?

Thanks in advance.

Could you share a screencast with this issue, please? It would be great if you could share the project file in the DMs too.
