slide-show conundrum

We uploaded a microsoft ppsx slideshow that was set to loop automically, however, for some reason or another, it didnt and only changes when we hit the space bar. To further complicate matters, i tried to play around w/ the files and libre crashed and when it came back - now the slide displays on our tv w/ the current slide in a big box and says current slide 1 / 31 above it - and next slide in a smaller box to the right of it and a bunch of stuff across the bottom of the screen. I later found out the slide show they provided me couldn’t be edited - so now i was just hoping to be able to return the slide show to the full screen view where i have to click enter. I realize this sounds really confusing but i’m totally stumped so figured i’d send this out as a hail mary. Any help would be greatly, greatly appreciated.

Have you tried closing LibreOffice and opening the ppsx again by double clicking on the file?
