Multi calendar dates not aligned with actual booking dates

[Andrew45]

When I look at the multi calendar [the one showing all 8 of our properties on one page], the dates are arrayed across the top row, with a row of boxes, one for each property, under the dates.   The date boxes are wider than the boxes for each property, so as you scroll right, they get out of alignment until finally on the rightmost side, they are a full day off.  One must be extremely careful to verify what date on the center or the right side of the calendar is actually booked - it's easy to make a mistake if you're not.   Seems there should be an easy fix for this.
