This is deliberate.

After you insert something to the database, Class::DBI has no way of
knowing what the database actually holds. There are lots of reasons why
the database would change what you give it: default values may kick in,
values may be truncated to fit column lengths, triggers may completely
change everything, etc. So we just discard everything and re-fetch it
when next requested to make sure we have the correct values.

The create() trigger allows you to change this behaviour.
