Cacti is not monitoring the correct host... How do I change SNMP target?

cacti

I have been handed a Cacti server that monitors a few hosts.

I noticed that three of the targets were displaying the exact same data - the cacti machine, machine a and machine b.

After doing a bit of digging, I noticed that machine a and machine b had "Local Linux Machine" set under "Host Template".

I have since changed the host template to "Generic SNMP-enabled Host", however, all the graphs still only display data from the local cacti machine (Updates every 5 minutes - I changed this yesterday - 12 hours).

I can't think what else is wrong and was wondering if anyone knows/can recommend anything?

There's the odd forum topic about an error similarly obscure as this, but I haven't seen any for snmp_count in particular.
