All Somfy Shade (Zebra Blinds, Graber) stopped responding to commands. Z-Wave Repair failed on all blinds

I was able to get one repaired and online. The other two give me the following error when trying to repair:

Z-Wave Node 1A: Repair failed node unreachable
Failed Nodes: 1A

I guess I need to remove and re-add. Do you know the process for this?
