motion detect set up error

[trapper]

hello I have the Dahua nvr with 4- dahua 5231 cameras connected the system works great except I deactivated motion detect on the system because the neighbor installed Christmas lights and was bombarded with alerts. Anyway went to turn back on and only camera1 will motion detect. I set it back to default and selected copy to cameras 2/3/4/. message says motion setup error camera 2/3/4. #1 works great. I don't know why #1 it won't copy to the other cameras. I tried to set individually and same error. any work arounds would be great. these cameras were purchased on form from empire candy great cameras.
