BUG: Changing data templace does not update data source name

[BSOD2600]

Using cactid 0.8.6b with cmd.php on Windows 2003.

I had a data source that was called "Cisco UBR924 - Upstream Power" which was using a template called 'snmp generic OID template" Data source name "(snmp_oid)". It has a graph template associated with it that uses the snmp_oid, data source (and others).

I created a new data template called "DOCSIS - TX" which has a data source name of "docsis_txpower" I also created a new graph template which uses the new docsis_txpower data source name (among others).

Then changed the data source, Cisco UBR924 - Upstream Power from the generic OID template to the DOCSIS - TX one. The name changed itself now to "Cisco UBR924 - TX" and shows its using the "DOCSIS - TX" template. When I went to use the new graph template I created, the friendly data source name, Cisco UBR924 - TX, was there but using the old data source name, snmp_oit.

When I switched data templates, shouldn't have the data source name (snmp_oid) changed to docsis_tx ??
