This is indeed very strange. My MN always pay to the same address of my masternode but it didn't break my setup at all. It's on the same address with different input so that is basically a separate entity from my masternode. Though I have no technical skill to help you on this one, I'll suggest you to contact the team in their Telegram
[1] channel. The team's admin there is always present and help everyone regarding their technical difficulties. Go and reach out to them to see what they can provide to help you on your problem.
