strange data problem

[dylan12000]

Something’s gone awry with data presentation in the app.

Check this screenshot from last week. Total litres=301

Now look at this one from this week. Total litres is down to 71

When I look at the list of fuel up logs, the app is showing fuel ups of something along the lines of 5 litres at £5/litre

When I click to edit the entry, the edit screen shows the correctly entered data.

Any idea what’s up here?
EDIT:
Am using v3.1.9
When clicking to edit in the app, it is entering the "last odometer" reading automatically, and I can't edit that.
