First one is "L", therefore no problem.

There was my problem. All the datasources were correctly added, but I didn't
check for UNKNOWN values. Now it is 0,l0,UN,0,l0,IF,+,l1,UN,0,l1,IF,+, ...

That helped a lot because I found the problem, that the cdef calculation
ignores
all values older than the last UNKNOWN.
