Question about presenting proof of income in Digital nomad D8 visa

Hi, I'm considering applying for the digital nomad visa in Portugal and I had a question for anyone who's gone through this process.

When you are providing proof of income by presenting payslips, which I believe the minimum is 3, do they have to be the 3 most recent payslips? I have been working remotely for the same company for almost two years, but for the last two months I took a vacation and my income from those months is lower since I am paid per hour of work, and therefore does not match the requirement for the visa. However for every other month before that it does. Would this be a problem when applying? Even if I can show proof of income for all months prior to the last two and that I am resuming my normal income?
