how to update datagroup parametric cell definition

having started hooking up parametric cells to datagroup catalogs, next question is how do i update the definition? 

I have updated the cell, however, even in new files, the datagroup still seems to be using the original version. So confusing. 

See images below. This is in a new file, no cells placed, I place a door using datagroup[ door tool, the shared cell definition from the original version of the cell is placed, not the current cell. 
Where is this definition stored in the datagroup, why does placing in a new file not place the latest version of the cell. 

Does anybody test before releasing software. waited months for perforators to work, and then have to deal with this!!!!!!!!!!!!!!!!!! Simply not good enough
