This has been a known problem since 2007 (BB342500). When a constituent is partially soft-credited for a gift, the full gift amount is being credited on the Appeals Tab of that soft credit constituent's record. For example, Donor A gave $4,000 and a soft credit amount of $1,000 is given to Donor B. When you open Donor B's record, it shows a $4,000 gift on the Appeals Tab, when it should only show $1,000.
