I am using Quicken for Windows Year 2018 Version R11.20.
I am going to post screenshots of 4 different reports in Quicken that should all show the same thing, but because of a bug do not. Note, I spent 3 hours online with Quicken support, with a gentleman that was actually quite knowledgeable, but alas, he ultimately said, "I cannot help you and there is no protocol for escalating issues to the programming team, please post your issue online."
Screenshot 1: Portfolio Value Report with the bug. Notice: 1) the cash line item shows up twice (it should only show up once as you will see from subsequent screen shots), 2) the account total only reflects one of the cash line items, 3) the total investment line reflects both of the cash line items. The bug is that the cash line item should only show up once.

Screenshot 2: Portfolio Value and Cost Basis Report filtered to show the account above. Notice that there is only 1 line item for cash.

Screenshot 3: Generated from selecting Investing on the ribbon and then Portfolio. Notice that there is only 1 line item for cash and the account value is equal to cash (because cash is the only asset of the portfolio). Sorry that the writing in the picture is so small. I am hoping you can blow it up so you don't have to take my word for it.

Screenshot 4: Generated from going into the register for the account. Look at the last transaction for the month (5/29/08), notice the cash balance. The cash balance is equal to the single line item for cash. Sorry that the writing in the picture is so small. I am hoping you can blow it up so you don't have to take my word for it.

I am hoping that the reader can clearly see that there is a bug in the first report.
BTW - this error is just now appearing, I believe, because I spent yesterday cleaning up some old transactions to make them consistent with the original brokerage statement.
If the writing in the pictures is too small, I am happy to send them direct. In addition, I am happy to provide any additional information that one needs to opine on this issue.
Please help. I rely on the Portfolio Value Report extensively and I have over 10 years of data in this portfolio.
Thank you.
