As the user manual describes: ‘additional start times that run over to the next day will be ignored’. What this means is that if you have a program that starts at 23:00pm, and repeat every 2 hours twice, then only the start time at 23:00pm will run. The additional two start times (which would have occurred at 1am the next day and 3am the next day) will both be ignored. The reason these are ignored has to do with how the scheduler works — it will only check programs whose first start time falls on today. Ideally it should also check programs whose first start time falls on yesterday, but this is more complex to check and hence it’s not implemented yet.
“Also two other channels were turned yellow and some strange figures appeared.” — can you be more specific? Do you have a screenshot?
