Sorry Mike. I personally know of many problems w/ the Capital Gains reports. What problem are you seeing?
In this case from what you have already tried, I would now be deleting and re-entering both sides of the trade - delete the sale, delete the Buy, re-enter the Buy, re-enter the sale. By any chance in Quicken have you had previous dealings with these two securities? If so, it is possible that a prior sale may also need to be deleted and re-entered. That is, the core issue may be related to those prior holdings, even though they are now closed out (or should be closed out). I have seen this type of thing happen maybe every 5 years or so. It seems to be a form of data corruption. It may be related to transaction entry, computer crashes, program upgrades, or some other unknown cause.
