Two accounts show up in summary view for one account

I think what you mean here is that you get a display that includes securities from what you believe should be two different accounts. The Holdings pane on the Summary tab only shows securities, not accounts. (Single Mutual Fund accounts often create problems and confusion; one of the confusions is that people frequently name the account exactly the same as the underlying security, then forget that there is a big difference between a security and an account.)

The first thing I would check is whether you have somehow altered the account so it is no longer a SMF account.

I would also create an Investment Transaction report for that account for "All Dates", and look for transactions for both securities.

This is a very strange observation. The market value is the number of shares multiplied by the price (it's not a stand alone field; it's computed). Difficult to see how Quicken could screw up one multiplication out of a great many.

It's always possible that you have some corruption; the only way to fix it (short of sending the file to Intuit) is to Validate. Validating does not find or fix all corruption. Make a Quicken "copy" of your data and Validate that. If the problem is found and fixed, make the "copy" your regular Quicken fileset.
