Cron expression not working


I use Hangfire in ASP.NET MVC application with MSSQL.
using this cron expression: * 22-23 * * 0,6
the next execution says at 23:40 “in 20 minutes”

Although the popup says it correctly: every minute between 10PM and 23:59PM only on sunday and saturday

In case the huor is adjusted, the jobs runs only every hour instead of running every minute.
In cas I use * * * * * OR Cron.Minutely() it runs every minute, that is correct.

What is wrong?
