Hungary v San Marino

I don’t understand these odds, Hungary beat San Marino 3-0 in San Marino earlier in this qualification group, Andorra beat them 3-0 in San Marino last month, Albania beat them by 5 in September, surely Hungary win this by at least 4 goals and betting the -4. I make Hungary about a 5 goal better team at home than San Marino.
