You need to remeasure the 729 colors into that file; not only because  
it's named
that way, but because the file itself is internally configured that  
way. (The
software will always use this file as a container for 729  
measurements, no matter
how you have it named, and there's no way for you to override this)

Likewise, you can't change that file to behave like a true "extended  
grays" file,
for the same reason (to save yourself the time needed to remeasure the  
extended grays).

Your only way forward is to remeasure the 729 colors, in the colors  
file; and
to create a new file specifically for extended grays (you HAVE to do  
this by
selecting the proper "template" first) and measure the grays into that.

When in doubt as to which kind of file you're measuring into: switch  
the display mode
for an open Target window to Pure. It will SHOW you what you should be  
measuring. Never
measure the wrong target into the "wrong" kind of Target window  
configuration.
