I have discovered what I think is a bug in Billings. Only problem is, I'm not exactly sure when it happens. It's happened several times, though. I'll describe it with an example. Say I have a client called XYZ Company, and my contact person there is John Doe. Now say I also occasionally do some personal work for John Doe that is not related to XYZ Company. In my Address Book, I have a company entry for XYZ Company with John Doe as my contact, and I also have a separate, personal Address Book entry for John Doe.

In Billings, if I create projects for XYZ Company, they will remain there for a while (a matter of days, perhaps), but later I'll find them all grouped under the entry for John Doe. I have a few different cases like this (companies whose contact people I also do personal work for), and when this bug happens, it affects every one of them.
