Issue with Project Invoice Line Grouping by Location in Time Entries

The project invoices are not grouping charges correctly.

That project is Charge-Based

When I make time entries for two different locations on my project, even when the service items for all entries are identical, the subsequent generated charges and then invoices separate these entries by location.

For Instance:

In the week starting August 21st, I logged 14 hours (8+6) in Calgary and 5 hours (4+1) in Ottawa.

I expect the system to consolidate this into a single invoice line for these combined time entries.

However, upon generating the charges and invoice customer, grouping issues arise.

After generating charge, I have those charges generated.

Upon reviewing the generated invoice lines, not only are the location field values incorrect (the second line should read "Calgary" instead of "Ottawa"), but it also doesn't combine the lines as expected.
