I would say that the 6 hour playout policy was causing the issue. You would have had to have 6 hours of unique artists to fulfil the requirements.
The next version of PlayIt Live will try to give a reason why items are not being scheduled into the log which will help to avoid this problem in the future.
How many songs are in the Swing & Big Band group? I can see from the list that you have another playout policy, can I see that? Please can you also post a screenshot of the version you are running (Help > About).
How can i repeat my log??
i have created one day log and i want to put it on next day with little change how can i do??
This sounds like a playout policy issue. Can you post screenshots of your setup, and maybe we can help?
