Thanks for posting your concern here in the Community, info-rumbleinroc.
For me to assist you, may I know what specific details happened on your income account showing as negatives? Do these income transactions appear as a negative amount when trying to run a report? How are these shipping paid shown as an income? We'd appreciate it if you could also provide us with a screenshot to get more details on what's happening on your end.
Any additional information would greatly help me provide a suitable solution to get through this.
