As Scott said, this is a known issue that is solved in TestStand 2.0.1 which is now available to order from:
http://www.ni.com/upgrade
In TestStand 2.0, the numeric format of a numeric property is Not saved if you leave its default value set to 0 (for the low limit property and for any numeric variable or parameter) or 10 (for the high limit property).
As a workaround you may change the default value of the numeric property to something different than 0 or 10 (as explained above). If the low limit (or any other property) needs to be set to 0 before the comparison, you may set its value at run-time using the "Pre-Expression" text box of the step's properties window. The pre-expression should be something like this:
Step.Limits.Low = 0
(Remember: The defau
lt value of the low limit should be different than 0 in order for the numeric format to be saved)
I hope this helps.
