Tutoring failing immediately [FM17]

[allyc31]

I see this happen quite a lot and wondering if anyone knows the reason for this?

Here's the latest example

Bought 22 year old Lascelles from Newcastle and gave him status of back up. He has a balanced personality.

Ask Jagielka, squad status of Rotation and personality of Resolute to tutor him. Everyone agrees this is a good idea. 

2 days later i get a notification stating that no way Lascelles could learn anything due to 'clear difference in personality'.

This isn't the first time i've seen this exact thing but it's the most annoying as i planned to turn Lescelles into my future captain. I know i can still do this but my head cannon is a bit ruined now.

Anyone know how to fix this? 

Thanks
