Schema mismatch - ad_weight_probability

I've updated to 2.4 from 2.2. Is this anything to worry about?

ad_weight_probability
column aid - differences on: unsigned, default
declared: array('description' => t('TODO: please describe this field!'), 'type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE)
actual: array('description' => t('TODO: please describe this field!'), 'type' => 'int', 'not null' => TRUE, 'default' => 0)
column probability - differences on: length, unsigned
declared: array('description' => t('TODO: please describe this field!'), 'type' => 'int', 'unsigned' => TRUE, 'length' => 3, 'not null' => TRUE, 'default' => 0)
actual: array('description' => t('TODO: please describe this field!'), 'type' => 'int', 'not null' => TRUE, 'default' => 0)
