Currently when looking at the dweller menu, if you select the sort option, it sorts based on room. This means you have to go down past one stat type before you can see the next one.
What should happen, is when you click on sort, you should see ALL of the Stat at Maximum Level's towards the top or at least bunched together.
Secondly, a second click on a column sort should sort it in reverse. This doesn't seem to exist at all.
Some serious quality control seems to have been skipped over in the process of rushing the application out to the platform.
