I think there is a bug with the gateway connection list, in the settings of a dataset. It's currently showing two options, one of which was an old gateway we removed some time ago. This gateway is not available under manage
gateways, and as such can not be removed.
This behaviour is consistant across report datasets old and new.
The top one in the screenshot is the old removed gateway.
Thanks for any assistance you can offer to remove this old entry.
