3818020 - Why am I seeing "Information added from different sources has been combined into single expense" in the expense with my Available Expenses?

I am working on my expense report and when I look at the Available Expenses, I see a notation above the Expense Type, date and amount of the charge that advises  "Information added from different sources has been combined into single expense".  What does this mean and how can I get the message to clear out?
