Mismatch with Database

Hello Everyone, I would like to ask why everytime I repair & rebuild the SuiteCRM this error always appear.

Check my vardef:

$dictionary['Account']['fields']['account_code'] = array(
    'required' => false,
    'name' => 'account_code',
    'vname' => 'LBL_ACCOUNT_CODE',
    'type' => 'int',
    'readonly' => true,
    'len' => 11,
    'auto_increment' => true,
    'unified_search' => true,
    'full_text_search' => array('boost' => 3),
    'comment' => '',
    'duplicate_merge' => 'disabled',
    'disable_num_format' => true,
    'studio' => array('quickcreate' => false),
    'inline_edit' => false,

My Accounts Table:

I hope someone can help how to resolved this issue.

Sorry for asking the obvious, but just to check, have you tried clicking Execute? Try it.

@pgr , done doing several times. I always doing build rebuild after some modification.

Can you specify your SuiteCRM version? If it is 7.10.1
This may help you

@sagarjaydeep , I am using 7.11.19
