Log Viewer not filtering channel joins + parts

[Coldblackice]

In Log Viewer, logs are full of channel parts + joins, which clutters the logs to the point of being difficult to follow conversation threads (if there are many parts/joins in between comments). I disabled the setting "Log joined channels history", but it hasn't stopped the logging of joins/parts. I believe this may be a non-functioning setting, unless I'm misunderstanding what the setting is actually for.
