Problem with template graphs

[Godzilla]

I tried to make a graph from templates but there is an error.
It does not add a different name for each graph when I add the first item to the graph. It is just adding the same item to the same graph and a sql error occurs.

Is this a bug in graph templating? Thanks

OUTPUT below:

[Item added]

Graph '*** TESTING {HOSTNAME} *** ' added
Added Item 'Ping Test' for graph ''
Graph '*** TESTING {HOSTNAME} *** ' added
Added Item 'Ping Test' for graph ''
Graph '*** TESTING {HOSTNAME} *** ' added
Added Item 'Ping Test' for graph ''
Added Item 'Ping Test' for graph '*** TESTING {HOSTNAME} *** '
