Version: CiviCRM 5.7.4/5 (patched for Contact images)
A Donor sent in a chq for $100 - Staff entered originally as a Donation. Then Edited the Contribution to make it a Memoriam Donation. CiviCRM generates the three entries - see below:
Issue: in Contribution Detail Report this Donor is listed as having donated: $300 - please see below. So somehow sums up the absolute value of the three amounts/financial account transactions that are linked to the single Contribution.
Question: why? Columns checked: Donor Name, Donor Email, Donor Phone, Financial Type, Payment Type, Check Number, Transaction ID, Date Received, Amount, Credit Card Type, Country
Update: there are no soft credits on this Contribution and the report is configured to pull Contributions only
