@Alice595 hi. Thank youfor your answer.
All three lists have the same settings. Check in same day until 11pm and checkout at 10AM. I don't need Preparation Time. For Custom rules I have "None".
The mistery is exactly this. All lists are exactly similar but just the calendar of Fresh&Clean has automatic blocking everyday at the same time.
Many days and hours with CS and nobody figured out this mistery. Nobody gave me a solution.
After thin about I thought that the best solution would be:
1st: block the Fresh&Clean list calendar until November30.
2nd: Redone the list with another name, same pictures and open the calendar until November30.
Opinions, and ideas are very welcome, thanks
