I just noticed this odd behavior - most likely it is expected and look forward to your comments.
I am maintaining a few accounts in the "Separate" section including an investment account, which I know by default they will be excluded from the reports. So, when I go to this [separate] investment account's register and select Holdings, it shows the list of securities. So far so good.
When I click on a security, I expect to see the Transaction history data but the pane is blank - as in the attached screenshot. Ditto with the Security Report for the corresponding security.
Again, I do understand that separate accounts are excluded from reports and net worth etc. by default, but I guess I was 'wishfully' expecting to see the transaction history data if I accessed it directly from within the account's register (without having to "Un-separate" it). Interesting that I just noticed this after all these years. Perhaps this can be turned into a new idea if it makes sense? Your comments are appreciated - Thank you.
