You cannot have two versions of the same module installed at the same time, so I wonder if this calendar module is a third-party module that you are running parallel to Events module 3.03.08? Or (and that seems more likely to me) did you upgrade Events module 3.02 to version 3.03.08? If in doubt, please have look at 'Host > Module Definitions'.

Does your problem happen with one of the default DNN skins (DNN-Blue etc.)? If so, what theme do you have set for the Events module (Default, FixedBlue, Small,...)? Also, a screenshot could be helpful.

If this happens with a custom skin or container only, I guess it's a tableless skin/container with floating DIVs. In this case I think it's best to contact the skin designer.
