STAPLER_NULL doesn't clear database fields.

[kkeiper1103]

I'm sure I'm just missing a configuration setting somewhere, but when I set my attachment field to STAPLER_NULL, the file is deleted, as expected, but the fields in the database are not cleared. I've read through the documentation, and it seems this is a bug.

I'm using Laravel 5.2 and Laravel Stapler 1.0

Here are some links to the code that doesn't seem to work right.
