Duplicated graph template not available for select

[jlo]

First, I duplicated a built-in graph template - "Interface - Traffic (bits/sec)" and give it a new name "Interface - Traffic (bits/sec, 25Mb)".

Second, I go to "Data Collection > Data Queries > SNMP - Interface Statistics". Add this graph template for this data query. All its settings were copied from "In/Out Bits". And I name this new associate "In/Out Bits (25Mb)".

Third, I go to "Management > Data Sources". Select the target device and the interface. Set "Output Type ID" to "In/Out Bits (25Mb)".

Forth, I go to "Management > Graphs". Select the target device and the interface. In the dropdown box of "Selected Graph Template". "In/Out Bits (25Mb)" is not show.

What am I missing?
