[Observium] printing page looks weird

Hi All,

wondered if anyone has seen there printing page to look like this?

for some reason I have the Toner graphs first then the Toner table underneath, but under that again is the Pagecounter and Waste Toner Box ?

the page looks laid out weird and incorrectly ?

what also weird is the toners for my Ricoh MP C400 is all showing as -nan% ??? and the levels as -3% or -2%

i have included screenshot showing what i mean

Regards

Simon
