[logback-user] Config doesn't work

The config shown below is creating the file, but nothing is writing to it,
and some classes are not logging at all. Those that do log, it's all going
to stdout. Obviously, I've done something stupid, but I can't figure out

Here is some output from stdout that looks like it's from logback:

Got 12 errors.
INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug
attribute not set

I would really appreciate a suggestion as to what I'm doing wrong.

Thank you,
