Cannot turn off Retry message in Knowledge Check Questions

Hello

I have some Short Answer Knowledge Check Questions that I want the student to attempt once, then go to the next slide which reveals the correct answer. The reason for this is it would be nearly impossible for the student to enter the exact correct response, and providing multiple attempts until they get it exactly right would be frustrating to them. I just want them to have a try at it once, then go to the next slide with the answer.

So I untick "Infinite Attempts", then let No. of Attempts = 1, and set the Success and Failure actions to Go to the Next slide. This seems to work until I add other questions, then return to these Knowledge Check Short Answer slides to find it has put the RETRY MESSAGE back, and reverted back to selecting INFINITE ATTEMPTS.

This seems like a bug, am I missing something? Is it even possible to do it in this way?

Thanks,

Veronica
