Threshold showing lots of RRD

[LiamRackSRV]

Hi

We are having a weird issue with cacti that we've been unable to find a pattern as to why this is occurring. Some of the threshold templates are showing alot of rrd sources as n/a (These shouldn't be enabled), this isn't showing on all templates and only some, I've attached screenshots of the correct sources and when this is wrong.

Has anyone experienced this issue before and able to provide some guidance on how we go about resolving this?

Cheers
