I see a Common Stock round for each of my companies, but I didn't create them. Why are they there?

Seraf used to automatically create a common stock round for each company because all companies have an initial capitalization structure to reflect the split of ownership between founders and for option exercises to convert into. That way if you received options or warrants convertible into common stock, the round was already created for you. Likewise, if your preferred shares converted into to common stock, the common stock round was already created. Seraf no longer automatically creates a Common Stock round for you.
