Skip next itum

Since this weekend I have load on demand .
Yesterday during the show I almost got a heart attack.
At the full hour whe have news and before the news are 2 short jingles.
Evrything after the news is linked (also the 2 jingles before )
What happened yesterday not the first jingle was started but the hole block was skipped .
Is there something in the log why mairlist skips things and can I scan the playlist before I start to rule out this kind off errors .

This isn’t new I seen it before but now I couldn’t do anything about it cause the player was set to next playlist .

And if you load on command the next color (green ) doesn’t show it’s only playing color.

At the show start there is a similar set of jingles and news what never gives problems always the block of the second hour.
But one weak its fine the other weak it skips.

Loaded the playlist off Sunday deleted everything until 2 records before the news. (switch off load on demand so I can see what record is next)
same thing ,Next is the news but the next (green) in playlist is the first after the first record after the news If I let the record before the news play out and when it stops the green playlist line is the news what it should be in the first place.
There is nothing in the log file.
the news is 6 files linked and the first record and the are all skipped, look in the first of the 6 files and it only says linked to next itum (music file before had nothing)

I only use assist with the link button in the playlist.
Why skips mairlist the hole block?
And where do I look in mairlist to find the course ?
