There's no "repair" function, so this is not possible.and that mediaportal is able to repair its self automatically if the schedule is set further into the furture
I think it's entirely possible that sometimes the act of creating a schedule with the KODI plugin breaks the scheduler... and sometimes it doesn't.
The challenge is to understand the difference between the two scenarios. Is it something to do with the schedule type, the program that's being recorded... (the list goes on)? For that, more log files would be needed. Ideally log files that show TV Server startup right through to the start of the problem.
I don't understand this comment at all.and that KODI is tricking mediaportal so it can't doesn't realise when the date is the 2nd of the the month the first of the month has already past.
