Investment account value does not match the market value shown on account overview

Old Rabbit

An investment account total value does not get updated correctly. When clicking on the account and drilling into Account Overview popup, the total in Market Value column at the bottom is shown correctly. But the value for that account on the account summary on left panel shows a different number. I have this problem only with one of my investment accounts. I updated and reconciled the account several times but the mismatch remains. Different values are shown for the same account on the account summary and on account overview. Is there a way to correct this mismatch? Any advice would be appreciated.
