App Library groupings

On the screen with the groupings of apps along with the app library how is it decided what to label the groupings?

For example the British Airways app is listed in the store in the category Travel but is grouped in an area called lifestyle.

How is iOS deciding how to group the apps and what to call that group?
Our app isn't appearing in any grouping at all, even though it is categorized as "Utilities" and "Productivity" in the app store.

My product team would like to know if this is a "Beta 1" thing or something we need to address on our end.
