I've seen that on my IRA and Roth IRA accts for years. I believe it had something to do with I converted IRA shares to Roth IRA back in 2010. But when I click on them, there is the mention of those shares but nothing to do. IRAs the cost basis is zero and Roth IRAs is basically the account value, so there is nothing to correct.

Now today I see that in my NQ acct too. If you click on it, it says there is nothing to show.
