i know this is probably a stupid question, but how do i delete sensors from within the panel and not on the server itself im monitoring?

for some reason the observium has detected lmsensors fanspeed sensors about 4 times over? and im not sure if its the server at fault or observium at fault, 

so i was just going to delete the old fanspeed sensors ?

i have attached some screenshots if people don’t understand what im talking about

Regards

Simon
