My Joshua Quarshie future stars evo defending stat maxed at 88 but should be 90

Hi Guys,

I had evo'd Joshua Quarshie using the Future Stars Academy evos where I put him in the below evos:

1. Future Stars Contract
2. Future Stars Midfielders (makes him 86)
3. All playstyles added along with roles and skills/weak foot
4. Future Stars CB first XI (88 rated)
5. Finally Future Stars Club Legend Defenders

But for some reason his defending stat is showing 88, although futbin/futgg shows it should be 90 rated. Find my screenshot attached.
