I am using the hole callout on a countersunk hole.  You can see that the document properties say the angle should be 2 dp, but it is showing 3.  

When I attempt to change the significant figures on the cs countersink angle, it also changes the dp on the diameters.

The workaround I've found is to set the hole diameters to 3 dp (Not using the default document settings.)  Then when I change the angle, the hole diameters stays as they should.  Is there something I'm doing wrong that's causing this behavior?  

2020SP3, but this behavior has been around since at least 2019
