Thanks Leo,

I do see the field name with the underscores. If the label is specified as such, it will render that way. But if the field label is blank, it should treat the values as spaces in lieu of underscores regardless of what values are next to it.

I'll test this out in a test version of LabKey using a version that is closer to the one you're running, but I suspect that this may have been user error since I can't reproduce the conditions so far beyond manually setting the Label of the field that way intentionally.

Regards,

Jon
