Problem flat file tag identifier found at wrong position

Hi,

I have a problem with the flat file tag identifier in a positional record, the tag is
700 at the offset of 24. But biztalk founds a different tag(200) at position 11
in a field that isn’t a tag field. It happens only when 2 fields are filled at
the end of the record(700) before, field ZZZZZZZZ and 8888888.

Records 300
thru 700 are positional records in a delimited record. Records 300 & 400 occurs
min/max 1, Record 600 occurs min 1 max *, Record 700 occurs min zero max *.

Does anyone have a solution?
