why soft deleting fields when ::Create

[SledgehammerPL]

I don't use winter soft deletion, but today I want first time use MyModel::Create method and ...

ERROR: column "updated_at" of relation "party_structure_organ_members" does not exist

(and also created_at)...

How to turn it off?
$guarded doesn't work...
