There should not be an issue here as you only have to answer this if such a question is explicitly being asked in a B-school essay. Otherwise else you may not talk about it if a gap is only a few months, because it does not affect your candidature.
Always keep your essays on a positive note portraying your leadership and team building experiences. Talk about times when you felt challenged, you motivated a team or drove a project to achieve impactful results. Such essays will get you interview calls for sure.
