Can't change time of calendar entries

I accidentally told DP this morning that I spent 3 hours on the wrong Zimbra entry.

I updated it to the correct time in the 'Time' tab.

I now have a total of 5 hours on the Time tab for 3/21/17:

But on the View Week tab, the Zimbra item isn't updating and is showing the incorrect number of hours.(I highlighted in yellow the incorrect entries)

This is also adding up on the Company Summary incorrectly:
