PVR Service Group Manager Crashing

So I have a tvheadend setup running on a separate pi to the one I have OSMC installed on, recently got bored of scrolling all the time to the channels I want to watch so thought I’d reorder them (Settings > PVR Service > General > Group Manager) as I couldn’t see a way of repositioning the channels I just moved them all into the Hidden Channels list and was going to readd them in the right order… Now that they’re all in there I can’t move them back, when I click on a channel to move it out of the hidden list and into the visible TV channels OSMC crashes and I get the sad face.
Any ideas?
