PowerPoint slides repeating

I have created a presentation, runs okay. I connect to a projector or online via teams, and random slides repeat, sometimes twice.

What's causing this behavior and how do I prevent it happening?

Hi @Tom Gardner,

Based on your description, I suspect that some PowerPoint playback settings like recorded timings, loop/kiosk mode, auto-animations, or non-linear navigation like custom shows or hidden slides, etc. make one slide may repeat sometimes. When you're presenting in Teams PowerPoint Live, there is also a possibility that attendees move around independently and then re-sync, which can make slides repeat.

To minimize the possibility that this issue may happen again, you can try these steps:

1/ Set the show to manual, non-looping

Go to Slide Show > Set Up Slide Show and check these settings:

  • Show type is set to presented by a speaker (full screen), not kiosk mode.
  • Advance slides set to Manually (or turn off Use Timings, if present) and ensure Loop continuously until Esc is unchecked.

2/ Remove auto‑advance from transitions

Select all slides, go to Transitions > Advance Slide:

  • Check the option "On Mouse Click”
  • Clear “After” so the slide doesn’t auto‑advance.

3/ Deeper check the repeat slides

  • Open Animations > Animation Pane on those specific slides and verify object with multiple effects and set them to On Click if available to avoid unwanted repeat

4/ Check for hidden slides / custom shows / action buttons

  • Go to Slide Show > Custom Slide Show for any custom show you may be accidentally starting, because custom shows intentionally run subsets of slides.
  • Any hyperlinks / action buttons on agenda or menu slides that may jump to a custom show and then return.
  • If possible, remove hidden slides since they remain in the file and can still be displayed during the presentation.

5/ For Teams PowerPoint Live and projector/second monitor presentation

  • If attendees are roaming through the deck, use the Private view toggle so they can’t independently navigate.
  • If you present to a projector/second monitor, the recommended approach is to use Slide Show > Use Presenter View and make sure Windows is using Extend with the correct presentation monitor selected.

    Thanks for the very helpful reply.

    I went through the presentation and compared it with your suggestions and no issue were notedm but your bit about using presenter view and setting windows display to extend could be a factor.

    Unfortuntely I don't have a projector, to practice on, so will have to wait a while and hope ;)

    Thanks again
