error: KeyError: 'show ; just print'

[yifans]

I built recsync on EPICS 7.0.2, Anaconda3-5.3.1 and CentOS7.
The client woks well. However, I found some errors when I started the server.

hello this looks like an error in the demo.conf

can you replace line 30
procs = show ; just print
with
procs = show

[yifans]

I replaced the line 30, but there were still errors.
This is the output.

@yifans Were you able to resolve this problem or is it still there? I see the same issue on Debian Stretch.
