MySQL query is not properly converted into SQLite query

I have a following query that breaks:

CREATE TABLE matches (
id int(10) unsigned NOT NULL AUTO_INCREMENT,
title varchar(200) DEFAULT NULL,
date timestamp NULL DEFAULT CURRENT_TIMESTAMP,
post_id bigint(20) unsigned DEFAULT NULL,
team1 int(11) unsigned NOT NULL,
team2 int(11) unsigned NOT NULL,
game_id int(11) unsigned NOT NULL,
match_status tinyint(1) DEFAULT ‘0’,
description text NOT NULL,
external_url varchar(200) DEFAULT NULL,
PRIMARY KEY (id),
KEY post_id (post_id),
KEY post_title (title),
KEY game_id (game_id),
KEY team1 (team1),
KEY team2 (team2),
KEY match_status (match_status),
KEY date (date)
);

Gets converted into:

CREATE TABLE IF NOT EXISTS wp_cw_matches (
id integer NOT NULL PRIMARY KEY AUTOINCREMENT ,
title text DEFAULT NULL,
date text NULL DEFAULT CURRENT_TIMESTAMP,
post_id integer DEFAULT NULL,
team1 integer NOT NULL,
team2 integer NOT NULL,
game_id integer NOT NULL,
match_status integer DEFAULT ‘0’,
description text NOT NULL,
external_url text DEFAULT NULL,
KEY team1 (team1),
KEY team2 (team2)
)

Any thoughts why it breaks and how to fix it?
