Grouping - Not Alphabetical

I am using “Grouping” to group a table by one particular field. I’ve noticed that A) the groups don’t appear to be correctly sorted alphabetically and B) If one group has more records than can be displayed at once (say 25) Knack will create a second grouping on the next page but it might appear after some other group. I can’t figure out what is going on - is it a display problem or and “on the fly” sort of the data base.

I have seen someone else mention this before and grouping over multiple pages, so I am hoping that the Knack Devs have this on their list.
Currently, I just have the display as long as I can to try and prevent multiple pages, but eventually most of my tables will fall into this problem also.
