Strange error with speedtree Broadleaf after 5.3.1F1 Update

After i downloaded the Update, my leaves started to look like this:
It worked just fine before updating and only some of the leaves.
Re-downloading the assets isn't working either.
I started using unity a few weeks ago so i have no clue what to do.

 

I think its the Broadleaves_Card_Desktop.tga File thats causing it, but i do not know how to fix it.

 

Did you regenerate materials on the SpeedTree itself? That might fix it. Try downloading the free SpeedTree pack from the Asset Store, we fixed this bug but it hasn't gone out with the standard assets inside of Unity.

 

Thanks! Now everything seems to be in order.
