The problem is on the one labelled Metric, that is the one that displays the angular dimension lines extensions in the video.  I checked some settings to make sure everything was set the same initially but perhaps it is a software setting on one file ?

The file imperial file was the original template the second file labelled "Metric" was the second created version. Using the original i changed the -DWG setting and altered the dimension styles to have new conversion factors for the alternative units accordingly. Other than that i have not changed any settings i could attribute to the difference in behaviour. If that helps!
