This subject came up at Matrix Games regarding difficulties in placing units. I do not know if this is a common problem for other players, but the individual that brought this up is a seasoned war gamer. I also had the same difficulties a while back. It may be that others have had the same problem on placing units from the reinforcement box into a HQ on map or in the HQ list.
I'll just copy the post that somewhat explains it here.

This was the route...
Select the reinforcements tab
Select unit
Find location on map
Click location
Click reinforcements tab
Select unit (because it hadn't been dropped last time)
etc...
etc...
Boredom set in!
-been there, done that. I agree something seems off doing the replacements, but it actually does work. The problem is that the units are not selected in the way in which I consider normal, or even how units are selected elsewhere in WW1-like in the battle screens.
For whatever reason; to select a unit from the reinforcement panel, and assign it, you must click and drag in one motion. I you click to highlight the unit and release (which I assume is a normal thing for many of us)and the grab and drag-frequently it will not work. The movement of the cursor and clicking needs to be done in one "fell swoop". I've tested this time and time again-it works-no mistake about it.
I can understand your frustration at this aspect of the game as I was there too. It is, however, easily corrected. Its just that it is not intuitive. It's something that one would do the right way accidentally and not realize it. After you see what its doing, then it is not a problem.
Anyway, try pressing and dragging for your replacements just to see if it works for you. At least you will know that you can come back to it when you have an interest and not have to face that ugly little circle of actions you described above.
Edit: This method of select (left press without releasing), drag and release/drop works all the time. It is much easier if zoomed in all the way though.
