Modified Toolbox parts Change back to Original

Hi All,

I have a problem with gears I generated using solidworks Toolbox. I made some gears then went "Save As" and saved them in another located in my google drive. I then modified these parts.

I added these modified parts to an assembly which works fine until I close and reopen. When I reopen the assembly the parts have changed back to the original unedited gears.

Any input would be greatly appreciated,

Jordan
