Bulk Insert (Column-wise Binding) doesn't insert all required rows

I try to insert 3 rows into "warning" table.
This table has trigger "after insert" that can insert 1 row into "unit_fault" table.

For example, after the second "warning" row trigger inserts 1 row into "unit_fault" table. it causes that the third "warning" row will not be inserted.

Triggered insert seems to break main insert without any errors.
