Why are dimensions switching to 9 decimal places

Using SW 2014 SP5

When I manipulate a dimension, such as checking "dimension to inside of arc" on a radius, the 2 decimal dimension switches to 9 decimals.  My settings are for 2.

Am I overlooking something?  This also happens when using the manipulator, for lack of a better term, it's the dialog box that appears when you click on a dimension and hover over the box.  Thanks!
