mistake in the points of Walcott

I have obtained 50 points this week but in the the table appears that I have 46.
I think that it can be due to an error with Walcott, who has not increased his total points since the previous week (40) and he has obtained 4 more this week (his mark was 7 in the sun)
I attache you the link:
