Perspective PowerChart - Discrerte logging for bool

Ignition Early Access
1

Is there a known bug in Ignition 8.3 regarding discrete logging of bools?
This is a tag is located on an remote tag provider with edge sync to central ignition server, where central is using the new core historian. On the edge unit the trend works fine (with default aggregation), but when I add the bool to a power chart on the central ignition server, this is the presentation when using “default” aggregation mode:

Changing to “Last Value” aggregation gives me the correct values, but still, this must be some kind of bug?

Another find from the same project:

Adding one pen, all good. Add one more and both returns “No Trend Data Source available”.
Remove one, the other comes back.

When both where bad, I changed the bool to “Last value”, and the other tag came alive.

8.3.2, one float and one bool.
