Where are my remotes?

I guess I missed a lot with regard to z-wave controllers, as last time I updated them was 8 months back. The way they’re handled have changed since then… my question is - where are my existing settings for the remotes? I used to go to the remote on Devices screen and change button/scene assignments, but now it seems they are all gone, and I’ll have to recreate assignments for all my 6 controllers? So, are the existing assignments are gone, or I just can’t find them?
