Icons for 'Distribute Horizontally' and 'Distribute Vertically' are mislabelled
This has been reported before, but is still wrong in the latest version of Acrobat. The icons for 'Distribute Horizontally' and 'Distribute Vertically' are labelled the wrong way around. They function correctly when clicked; it's just the symbols that are wrong. If you look at the same feature in InDesign and Illustrator, you'll see that Acrobat does not match.

Thank you, yes. I just wasted a fair amount of time trying to figure out why none of my fields would distribute. Annoying.
