[CE 10.16.00.080] Bug alert - interactive dwg referencing "coincident" missing

Seems there's a bug in the dwg reference attachment properties dialog box in CE 10.16.00.080:

1 - There's no "coincident world" option listed. 

2 - Hitting Ok will attach the dwg as "coincident world" 

So there seems to be 2 issues with that dialog:

1 - "Coincident world" shown as "Coincident"

2 - "Coincident" option is missing

Attaching using non-interactive options seems to works as expected:

If this is a known defect, if I can get a defect number, that would be much appreciated. 

Best regards,
