That's not a bug. Blank is the same as not-suspended. Blank means none of the ACTIVATE, SUSPEND, or RESET RESETOPT=(SUSPEND) commands have been used for the object or a set for which the object is a member.
Best thing for a quick response if you think you have found a defect is to open a case with support.
Thanks Paul. I guess just because I find it confusing doesn't necessarily make it a bug.
Now that I know it's normal, I'll adjust.
