Trendline not working in some Items

Setup, Configuration and Use Items & Sitemaps

Still as a beginner with Openhab 3:
Setup my System and now trying to generate the UI.
My problem ist:
Using the label card widget, I can have a trend line in the background. This works for some widgets.
But, some other widgets do not show the trend line, but seemed to be configured identically.
This works:
component: oh-label-card
config:
trendItem: FRITZDECT2001_CurrentTemperature
action: analyzer
actionAnalyzerItems:
- FRITZDECT2001_CurrentTemperature
item: FRITZDECT2001_CurrentTemperature
title: Wohnzimmer
actionAnalyzerCoordSystem: time
icon: oh:temperature

This does not show the trendline, the label works and analysis works also
component: oh-label-card
config:
trendItem: OpenhabSysteminfo_CPUTemperature
action: analyzer
actionAnalyzerItems:
- OpenhabSysteminfo_CPUTemperature
item: OpenhabSysteminfo_CPUTemperature
title: CPU
actionAnalyzerCoordSystem: time
icon: oh:temperature
iconUseState: false

Searched for the root cause without success :frowning:

Then, looking into the items, the same picture ( may be, the root cause is here ?)
Selecting the item in the item list, shows the current value on the top. And -sometimes- the trendline.

What can I do, if the value is shown here (and correct), but the trendline is missing?

Thanks in advance

Solved ( Don’t know how to close the topic ), but may be, someone else has the same problem:

Just removed a not working item from the same thing ( CPU Voltage ).
It ist the system info binding 3.01
Now it works

I have the some problem, but don’t find any non-working item in thing. The oh-label-card analyzer works, but trendline not displayed.
