Vimeo Block breakpoint problem

I’m using the Vimeo block in my portfolio posts and there seems to be an issue when the browser breaks past 1200px the Vimeo block justifies left even though I have it set to center. I’ve tried adjusting the break-point value in the global settings and it still has this problem. Please let me know if there’s any way I can go about fixing this. Thank you!
