openstudio values default to 0 instead of blank

Some input values in the OpenStudio application have a default blank (no value / null value). However, as soon as the field is selected, it automatically defaults to 0. There does not seem to be any way to fix this back to having a blank (null value).

This is important for some functions in EnergyPlus such as Field:Economizer Maximum Limit Dewpoint Temperature where if this blank (null value) there is no outdoor air dewpoint limit control.

Is there a way to force these fields to a blank (null value)image description?

You could edit the .osm file in a text editor to remove the value from that field, or write a script to call resetEconomizerMaximumLimitEnthalpy.

But I think this is a problem with the UI that you shouldn't need to do either of the above to fix.

Thank you Eric. Yes, I have been editing the OSM file, but thought there was some value that could be placed (such as null) using the UI.
