I have the exact problem.
My strongest skill is Computer Use.
My weakest skill is Treat Injury.
Kreia said that I must improve my weakest skill and then I will receive bonus for both: for strongest skill and for weakest skill
After talking to Kreia again I got the same message (as Nirvana24) which says that my weakest and strongest skills got bonus.
But unfortunately I received no bonus!
I tried many things (to talk to Kreia later, to use Treat Injury (i.e. use medkit), when leveling up to improve both skills (comp and Injury), to improve non of those skills, etc.) but result was the same - no additional bonuses.
I am really mad
