Paused slide continues, but it shouldn't

I am using Captivate 8.

An ongoing issue for me is when I have interactivity set to no action, the slide will still eventually move forward if clicked enough. I have never been able to rectify this and my courses always fail QA review for this reason. I have it listed as a known bug, but now my current project is having more issues than normal.

The current slide I have has three smart shapes being used as a button.

Each button is set to show a smartshape with text upon click.

On success: SHOW

The settings for each button are No. of attempts: 1

Last attempt, no action

No other display options are selected.

I also tried Infinite attempts, last attempt, no action and this did not work either.

I have a number of items on the page pausing at 1 sec.

No matter what I choose for settings, the second smartshape seems to be a problem if clicked more than once the screen advances. There is no logical reason I can find for this because it is a replica of my other 'buttons'.

Sometimes, once each smartshape is clicked, if the screen is clicked again it advances. I do not want it to advance. Is there a setting I am missing, or is this even possible? Why is the slide advancing when I've set everything to not allow it to advance.

Thank you in advance for your responses.
