That's strange, for me it works in V2.2.0-rc1-39.
Changes in Current Drawing Preferences are applied correct and immediately.
Also the Decimal separator setting does not match. In the Dimensions tab it is set to '.' (Period), but in the drawing screen shot I see a ',' (Comma).
I checked the Linear/Angular zeros too, this is to cut leading or trailing zeros, this work also as expected.
