pictures won't show correctly

After the latest update a few weeks ago, the picture don’t show correctly. I am trying to view the pics on a Samsung smart tv. A couple of funnies -

  1. I renamed the pics from 001-294 but the only one that shows in the correct order is 001. I did select a sort preference by name.
  2. I hit the arrow to start the slideshow and the time per slide doesn’t seem to matter. Even though I move it upwards to, say 10 secs, it still displays for only 3 seces.
  3. The pause doesn’t operate. Can’t stop the slideshow except to hit the back button which takes me completely out of the current pic set

It is possible I am not using the new update correctly but I can’t find a manual anywhere. Any suggestions would be greatly appreciated…
