This month I made two contributions to two different Savings Goals. When I ran a Spending Report, those two contributions show up under "Transfer" (although their amounts are excluded from the totals). In the listing, the Account is the one I charged the contribution against. The Payee and Tag are the name of the Goal and its related auto-created Tag.
A withdrawal I made (not shown in this image) also shows up in the same section of the Report.
I don't recall ever seeing this before. I was under the impression that Simplifi did not keep a transaction-by-transaction record for Savings Goal contributions, but when I run a report for earlier months I can also see the amounts and dates of contributions made back then.
