This usually occurs because you may not have the same document path as your colleagues.
You can check this by using the following steps (please note that you may need to ask your Dimensions Administrator to check and correct this for you).
Log into Dimensions
Select System Control, Users (ribbon menu) or System Control, Users, User Records (classic/module menu)
Locate the record of the user that is seeing the documents in the correct format and select the Options button
Select the Edit button
Select the blue arrow next to ACD Documents Location
Copy the path in the resulting window
Close the user record
Repeat steps 3 - 5 for the user record that is not seeing the correct format
Remove the exiting path and paste in the path that you copied in step 6
Save the user record
Both users will now see the same document format when producing documents in Dimensions
