Captivate 9 quiz fails to score correctly unless I unhide Results screen.

I’ve created what I thought was a pretty simple quiz using multiple invisible shapes, used as buttons, over images. One of these buttons on each
slide is set as the correct answer and included in the quiz.

All other buttons on the slide (the wrong answers) do not score or report.

We always hide the Results screen and instead have navigation set up to take learners to either a Retry or Next Steps screen based on pass/fail criteria. We’ve done this for years with no issue. However, this quiz fails to score correctly and navigates to the Retry slide – even if all the questions are answered correctly - unless I unhide the quiz results screen.

I’ve used Captivate since it was a Macromedia product and am at the end of my rope. I’ve also had a co-worker look to see if he can figure out why this isn’t working. You are my last hope.

Three more things:

I’ve had great success with this format before. Creating a series of pop-quiz questions throughout a project instead of a single set of question slides.

There are a total of 12 questions. I can’t use hotspots as Captivate only allows 10.

I have screen captures of settings, and tried to upload the images in both .jpg and .png format but was told this is a forbidden format though the instructions don't say what format should be used.
