Happens on both a C-5 and a C-7 that were upgraded from 2.39.?? to 2.4.0.143
Any devices that have an apostrophe in the device name display a blank device edit page. They still work, but I cannot change any device settings, etc. This is consistent across both hubs and across reboots. Don't want to have to downgrade but I will if this isn't fixed soon
