Tag history on system tag OPC "Connected" not updating

I’m finding that the powerchart will display the incorrect value for these tags. For example, here’s one of them with the value of True:

Just a thought, but perhaps create a new “Reference” type tag that points to these Connected tags and add the historian to these new reference tags. I do this, but on all my gateway network connected systems and it graphs correctly.
