Weird Quicken Premiere 2004 problem

I am using Quicken Premiere 2004. I set up a new investment account with a linked cash account in April 2005. I purchased two bonds using cash from the linked cash account in April. When I create a net worth graph, it reports that this account has a value equal to the purchase price of the two bonds in February and March. When I click on the bar in the graph for February and March, the program reports there are no transactions which is correct. Why is the net worth report showing that the account has a balance before it was even created? Any ideas? The transaction registers for the investment and linked cash account have the correct dates.
