Well, it's not a "problem"; it's the way DNS is supposed to work. When 
you delegate a zone to other nameservers, then those nameservers own the 
data in the zone, not you. The only exceptions are so-called "glue" 
records describing the nameservers for the child zone. Ordinary records, 
like A records which are not associated with nameservers, MX records and 
so forth, belong to the "closest enclosing zone", i.e. the child (or 
"child-most") zone.
