I am configuring Product Properties and am having difficulty setting the Default Value of some of these properties to 0 (zero). When I create the Property, for instance, Machine Height, I would like the default to be zero, and for the property to be non-required. Everything on the Property record appears to be configured correctly, but, when selecting a Quote Product and filling out it's properties, I find that the properties I defaulted to zero are blank and if i proceed without filling them in, I get a warning that a value must be entered, even though they are not required. Has anyone else encountered this? I've included some pictures. The images are all related to a property labeled "Access Height." Any insight would be greatly appreciated!
