Can't Defend Corners!

Every game I concede at least one goal from a corner. Match preparation training is set to Defend Set Pieces and has been for a while but no difference. Is anyone else having the same problem???!

It's a problem I'm hoping SI will fix.

Happening to me also, only recently. I've never changed my defending corners instructions but recently I've been conceding from a lot of corners

I've conceded a lot though that's because my defenders are shocking
