Iirc, there was an issue with that which is solved meanwhile.
There should be an option in Current Drawing Preferences in Dimensions tab.
It is called Linear zeros in current version, I think its name is the same or similar in 2.1.0.
When there remove right is checked, zeros behind the point should be removed.
The issue was, that all zeros on the right were removed, what is wrong of course.
So you can try to uncheck this or update to a newer version, e.g. 2.1.3 or latest nightly build.
In the 2.2.0 version it's by purpose to show text simplified as boxes when very small in relation to the screen, and so hardly can be read anyway, to speed up screen rendering. When you zoom in the text should appear. You seem to have a high resolution screen, maybe there is a problem with this.
