Mistakenly increased the number of editors

Hello! I received an invoice for the previous month, it shows 3 editors. I always work alone. By mistake, I added two members as editors, instead of viewers. But in fact, these two participants did not edit anything in the project, and were present only as viewers. You can check it out. Please change the bill, I will not be able to pay it, because in fact I work alone and no one will compensate me for this. I hope for your understanding.
