Accessing keyframed channels in curve editor

[biglittlepictures]

Ha, yeah Scale operator, apologies 
Here's a screengrab of the curve editor with the TyFlow selected and filter options shown, it appears that there's no controller assigned to the channel (the option to add one is also unavailable in the quad menu if that's any help).

I am having the same issue, can't see the curves to edit, but they do show up as red ticks inside tyflow, i just can't edit them after creation because they stay invisible.
