Making Exceptions all but first exception working??

Hello, Hankan or anyone that may have the answer to this. I only need to show 2 specific onpen days in the month in October. I have working days set the Thurs and Friday which makes every thurs and friday available.

To remedy this I set exceptions for no working days for the remaining thursdays and fridays in the month. All of them show as greyed out like they are suppose to except for the first exception day. Anyone know whey this is doing this?
