Thold sending the wrong graph when emailing alerts

[Lamneth]

I have a few devices that I get various information from using a script and Cacti then puts the data into a single RRD. I have several graphs created from this single data source. When creating thresholds, it always defaults to the lowest graph ID that uses that data source for the graph associated with that threshold. If I change it in the drop-down menu and hit save, it says that the record was updated but doesn't actually change the graph associated with the threshold. Because of this, the wrong graph is sent when some of my thresholds are triggered. This can be fixed by manually editing the threshold in the database with the correct graph ID but I don't want to have to do that every time.

Am I missing something? Or is there a fix for this?
