Hide Thank you Dialog Slide Layer

How can I hide this layer from showing when the user moves from this ungraded freeform slide? I have two slides that I changed to not be scored, and it switched the slide layers from Incorrect and Correct to the shown Thank you Dialog. However, now those two slides are showing the Thank you layer and I don't want them to. I tried using the eye image on the timeline to hide all layers and that removes the text, but I'm still showing a white box with the green checkmark (second image below).
