The only date that matters on your balance sheet report is the last date of the date range.  That is the day the balance sheet is applicable to.  Double-check that the balance in your COA and BS are using the same date.

Also, check to see if you're running the report on cash or accrual accounting method (to the right and below the date range).  That will impact the balances on the balance sheet vs COA.
