Manually entering listening time

How does the listening time bar on my statistics work when I manually enter things? I tried adding two minutes and so put in 0:02. It then jumped from 5:1 to 6:2.

to enter two minutes you would do this

For hours, you would change the 1 to 0

for minutes you would write 2 - NOT 02, :02 etc

Oh, thanks! I probably left the 1 in the hours as well
