I had an error in a security ticker. I changed the ticker and selected the copy quotes from wrong ticker to TRLIX. The name of the security is TIAA-CREF Large-Cap Value Fund Institutional Class. Now the historical price only go back to the middle of 2017. Here is the screen shot of the Security Detail View.

When I click on More Charting and look at the prices online they go back to 2002. Now my portfolio performance reports are all messed up because they are pulling a zero price.
I went to the Update menu on the Security Detail View and selected Edit Price History. I put in a new price for a quarter end in 2015. No errors, but the price isn't there. In the Security List it looks fine.
When I try to add a price in the Holdings screen for 3/31/2015, Quicken Crashes.
Here's the online prices.

Any help getting this issue fixed would be most appreciated! Thanks
