The skill tree on my science officer has altered...

I now have 2 ensign skills... jam sensors at 9 which i had before this issue and now hazard emmiters lvl 1 has come from nowhere, giving me 2 ensign skills..

Yesterday i was using my lutenant skill polorize hull 2 fine, now it is greyed out on my lutenant science station as the 2 enign skills have filleed 2 available skill slots..

The polorize hull skill on my science station is now showing up as lutenant commander skill??? when i check my sciebnce officers skill trees it shows cleary that my polarise hull 2 skill is lutenant..
