I purchased a T-bill yesterday, 9-7. Didn't record it because I prefer to download the bond information from Vanguard. This morning the purchase dated yesterday was downloaded from Vanguard. Now there is a day gain of the purchase amount in the Investing screen.
I deleted the downloaded transaction and re-entered it. I didn't delete the downloaded T-bill information, though. I used it in the re-entered transaction. (Hope that makes sense.) The day gain remains.
Would appreciate any thoughts.
