Mode "Away" doesnt work?

Enable “Away” mode.
I try to log into the admin area – get on the main page.
It seems to be “Away” mode working.

set working time from 19-00 to 22-00

but at the same time, when the admin panel is not available, I see the logs blocked incorrect login attempts in the admin panel at a certain nickname.

as if this period mode is not enabled. although check – it is active.

it is a bug? plugin does not work properly? Explain why this is happening?
