Measure along Element does not display dynamically on reference file

I have a user that isn't able to measure along an element to where it shows the "dynamic" measuring (see image).

1 - Staring to measure from 64, a highlighted line starts and follows the cursor

2 - Finished measuring and have a distance (red arrow)

He doesn't get the "highlighting". The entire element highlights but no "thick" line as he moves his cursor. The file itself DOES measure along element but when referenced the file doesn't seem to work correctly.

ANY help or ideas is appreciated.

Thank you
