Unfortunately there’s nothing indicating that the problem you posted is related to your node. The screenshotted problem was related specifically to a node that had expired orders in the (now depreciated) database. Your unsent orders are related orders contained in the flat files, which is a different problem caused by file corruption.
You did find and detect the issue with your node (and fixed it). Unfortunately you found the problem only after payouts. The Storj is aware of the problem with unsent orders and they working to fix it.
This project is maturing and getting better with every release. Personally, I have been supporting this project for over 3 years now. This project is definitely worth sticking around for. The Storj team has always been responsive and fair when it comes to problems, and I am sure they will do what they can to make this right.
