Description Eyal Rozenberg 2022-05-30 15:33:51 UTC 
I have a multi-slide presentation, in which one of the pages has the following structure: A title box and a single content box; the context box has one paragraph with no bullet, one bulleted at level 1, one bulleted at level 2, and three more bulleted at level 1.

Each of the paragraphs have an "Entrance: Appear" effect.

When I move forward through the effects in presentation mode, everything is fine. But if, after the entire content is visible, I press the left arrow button, i.e. move one step back - not only does the last paragraph disappear, but also the first, unbulleted, paragraph.

Can't upload the entire document at the moment, may be able to whittle it down later on.

I've seen this in earlier versions as well, possibly before v7.
