Unfortunately there's not much you can do. It seems that the migration
process from 7.4.03 to 7.6.0 produced a catalog inconsistency, which
cannot be repaired with the current facilities.  
I recomment to suspend the affected table T, i.e.

RENAME T TO SUSPENDED
CREATE TABLE T LIKE SUSPENDED
INSERT INTO T SELECT * FROM SUSPENDED 
DELETE SUSPENDED (if possible)
recreate all views, synonyms, triggers etc. based on T
