Urgent - .toStartOfWeek not working correctly

Urgent - .toStartOfWeek not working correctly

Hi

Why are these formulas showing as some am and some pm? 

It means when I do a report I have two different values for the one date.

I would ideally prefer to have no time value if this is possible? But if not I would like all that fall under the same start of week date / start of month date to have the same am/pm value
