Working hours are not applied with extraordinary working days

Hi there,

I've got a problem with high priority.

Two service providers swapped a work day one. So one service provider (K.) has an extraordinary free day next Saturday the 21st. On the other hand, the other service provider has to work, so I set this date as a extraordinary work day.

Now, the agenda says that the service prodider M. works till 6 PM, however, the shop is open till 3 PM on Saturday. All working hours are set properly.

What's going wrong?
