Poller Performance Graphs Errors

I have problems with my Poller Performance Graphs; the Total Poller Time is broken. No errors in the log file. Also the output from ./validate.php is fine.

Polling 950-ish devices…

Screenshot from Edge Version 131.0.2903.146 (Official version) (64-bit)
Same in Firefox 134.0.2 (64-bit).

Output from ./validate.php:

How can I troubleshoot this further?

I get the same thing on my install. I get capture this in the librenms log.
