I analysed your document Final dwg.FCStd. I can confirm the issue.
It is a kind of the 'topo naming problem'. If the part has scale 1.0 the upper circle (diameter 16) is Edge34. After changing the scale to 2.0 the same circle is Edge26. The dimension keeps connected to Edge34.
I think it happenes, because your part has been imported from somewhere (a2plus ?) and therefore is a foreign object for TechDraw.
