Warning icon | Meaning

Is there a reason on why does a warning red icon appear at the title of some charts?
Attached you will find an example.

What does it say if you hover your mouse next to it or try to click it?

Hello TonyC. Unfortunately it shows nothing when I hover the mouse over it, and it is not clickable.

Can you share Admin ->Troubleshooting -> Diagnostic Info

Here it is:

Can you check if there is any error/warning coming out of the console:

It doesn't appear anymore :grinning:. Thanks for help.
