¿ soa record not found; can't increment serial ?

[DPH]

I imported 2700 domains into freeside from my name server. When I try  
to delete a record from the domain, I get the above error. When I first  
imported them they had 2 SOA's. The default one from the configuration,  
and the one from the imported records. I took out the default record  
from psql. Everything looks fine now, but I can't edit or delete them.  
They export fine. This is what the database shows for domain_record.

The SOA looks fine to me.  There are records that I have added manually  
to a customer and they work okay, I can delete any record and add new  
ones and the serial increments. But, all the ones imported can't be  
modified. The imported ones aren't assigned to a customer.
