So the bug is there, “quick format” should be reappear as available option in the Format window of the second partition once formatting of first partition is done. Like you wrote earlier. Do you acknowledge that this is a bug, or do you write it off as “expected behavior”, even though it makes zero sense from a user’s point of view?
In general, I don’t have a hard time writing bug reports, but with you, and just you, it’s a damn fight every effin time.
