If you add a Wipe or similar animation to a presentation you may find that the animation does not complete. There are two possible workarounds for this behavior.
Replace the Wipe animation with a different animation like Fade or Appear.
Add an additional object to the PowerPoint slide, and either make it invisible (by removing Fill and Line colors) or move it off the slide (so that it does not appear in the published presentation. Then apply an animation to the invisible object, so that it is the final animation for the slide.
