Problem with drawings

I am having problems with drawings since the last update. Before, I was able to change the scale, units for dimension, etc. Now, most of the options are missing, and the ones that remain don’t actually change anything in my drawing. If I open a drawing that I started prior to the update, it works fine. For example, here are the options available when I open an older drawing. All of the selections work, and there are more options.

Now, here is what it looks like in my newer drawing.
There are fewer options to select, and the ones that are there don’t actual make any changes in the drawing.

Am I missing some new setting, or is this just a glitch with the update. If so, is there a way to revert back to the old version?
