Power Chart not working for tags from DB Table Historian

I created a new Historical Tag Provider of the type DB Table Historian however, right now I am not able to display them in the power chart for some reason.

I am also experiencing the same issue. As soon as I add a pen from DB Table Historian, all pens disappear (also the tag historian ones).

What version of Ignition of you running?

I defined a DB Table History Provider: CVTrendlog

The table i am using as datasource:
name: trendlog
datum (timestamp)
tagname (text)
fvalue (float8)
quality (int4)

And the Pen Tag Path is:

Testing in a Perspective PowerChart component, Ignition v8.1.0
