Max/Min dimension spec quirk - did I forget how numbers work???

I rarely use the "Max/Min dimension" tolerance option but a recent drawing uses the USL-LSL callout scheme rather than the typical nominal/deviation limit callout. I figured I'd use it so the report conforms to the drawing spec. On every dimension I've applied this to I get the error in the pic. Apparently the CAD nominals are not centered in the tolerance and Calypso does not like this.

Obviously it's not a big deal to work around, but I think it's pretty funny that Calypso seems to think "not centered in tolerance window" = "Out of tolerance" and suggests I pointlessly change the nominal to dead center of the spec limits.

Are you saying that this would be flagged as OOT because your nominal is not 2.8575 but the result is within min/max tolerance?

The question looks misquoted.... In previous versions of Calypso, it would only say if you wanted to change the nominal if it doesn't sit exactly in the middle of the tolerance range.
