Month view events not positioned entirely within their days

When switching the the month view (I have day and week views available), the events aren’t being positioned correctly so part of them overlaps the preceding day. I looked at the relevant CSS properties and the events are being given a left property that isn’t the correct amount to shift them properly.

The events shows fine in both day and week views, the month view is the only one showing this issue.

I have also attached a screenshot.

Check custom css which you are using - it have some padding or margin for TD elements, which is affecting the view.
