Sorry it took me this long to answer. Yes, it was solved after save and reload. Thanks!
I am experiencing the same issue. It all started after I tried to offer contract to a player, and since I did not have enough funds, to not click "Walk Away" and get him angry, I clicked "Continue" (top right corner). After that, whenever I try to offer a contract to anybody, I get the same issue as OP. Is my whole save file corrupt now?!?! :(
