"Add Info" view is confused after switching to "History" and back

[dkg]

If i'm on the "Add Info" screen, on a day other than today, and then i switch to "History" (via the button at the bottom) and then back to "Add Info", the "Add info" screen shows today's date, but information about the previous day i had selected.

Here's me looking at today (July 13) in "Add Info", the normal way (note that nothing is selected for appetite):

here's me looking at two days ago (July 11) in "Add Info" -- note that "high appetite" is selected:

Then i choose "History" and then "Add Info" again, and i get this weird mishmash:

the top says "July 13" but everything below it is from July 11 (not only the appetite data: even the "two days ago" sublabel is wrong).
