Sample Scheduler Calendar Month view not formatted correctly

When I run the Sample Scheduler Calendar in week view and day view it looks fine but in month view the headings look right but the columns are not in line with the headings.

do you mean some of examples of the trial package, or one of the other downloads? Please clarify what the exact sample you using.
Btw, this seems to be related to your other post
Didn’t css from there helped?
