Frontierspace v1.75 leveling issue

    Hi! I have already made it up to level 8 in Frontierspace mod 1.75 and got stucked there, it says the requirement for the next level is a mission. Its not clear for me what mission is that, i've tried lot of normal missions and the Fugitive Person escorts (cargo item). If theres anyone who have made it that far and having similar issues and maybe solved it please give me a helping hand.
    Thanks
