Modified column does not show the date modified but show the date the file is added to vault

Hi Sir,

When I add SolidWorks files to the vault, the modified column will show the date the file is added. Please see below screenshot.

How can I show the date modified as shown in the second screenshot when I add the files in the vault?

When I add pdf or text file to the vault, I do not have such problem. I am using EPDM 2014 SP4.

Hope you guys can help. Thanks alot.

James
