I don't understand where the error came from if the OP used oprnet to calculate the OPR.
This has been discussed before but for those that didn't catch it, I will repeat it again. We should not compare OPRs across different regionals/district events. It looks like that is what the OP did. The reason is some events are stronger than others and it is not a fair comparison. The better way to do it is what I called True World Ranking where every match including elimination rounds of every regional/district are all assembled into a giant matrix so all interactions between teams are taken into account. It is not perfect but it will give each team one OPR number that is a reflection of their whole season so far.
This year I also calculated the OPR for hybrid, bridge, teleop and cooperition separately using the same method. I publish all these data after each week in the following CD link if anyone is interested.
