New document button adds calendar entry??

Hi BrinkyH,

I have to say the issue is a known issue in some version of SharePoint, and the same issue also happened in SharePoint Online, which has been fixed by a back end hot fix.

To fix the issue in your environment, please try upgrading your SharePoint to the latest CU, or you can remove the existing document library web part, and re-add it. Here's a link about SharePoint 2010 build numbers for your reference:
