Hello:
If I may make a suggestion.
It would help if you looked in the cfg and found out what they are.
One is a very old engine spec.52779:50002
Two is a very old horn.kuid:52779:54000
Open CMv.3.x
R click idem that is missing kuid, scroll down R click view config file,look for missing kuid number.
is it a horn?,bogey?,interior?,product?,ect:
This will help you to find/fix/or post.
