I'm not sure there is a good fix for that at this time. I use Lui for my overall UI but I use Shadowed Unit Frames for the actual unit frames and it's been updated to track shards. When I was using SUF on the PTR it couldn't track them so I used an old addon called ShardWatch. The downside of that is it's an old addon and can only track 3 shards. Hopefully there will be some new addons coming out soon to track our secondary resources for all specs.
NugComboBar, a rogue mod, currently supports soul shards. I'm still looking for a movable demonic fury bar however. It says NugEnergy can do it but when I installed it I couldn't see anything even when I /nen demonic fury in game.
