If you the lines on the calendar are not lining up properly to the dates or the bookings are overflowing into other rooms & dates then we have an issue with the zoom setting in Chrome.

Examples:

As you can see the its not quite correct especially at the bottom of the calendar.

In Chrome You need to press the 3 dots in top right corner of the screen. See below:

In the middle of the menu you notice the zoom settings, here i have it at 110%. This needs to be at 100% to work properly.

Make sure you get this back to 100%

Then the calendar should be correct

If you still have issues please contact support but also take a screenshot first so we can see what you are talking about.
