If you are seeing Jiro and he is not offering you a KDF boff then you are not yet at the full diplomacy rank.
Or it might be that you have not taken a mission. You should have gotten a directive to go and see Jiro when you hit your diplomacy maximum. Check your mission journal and see if it is there but not taken.
Thank you everyone for all your suggestions. But know that I tried all those prior to coming here. I find this situation comical at this point. Anyways, if anyone as something new to mention in this thread, please, dont hesitate.
Before logging off earlier, I sent a GM Ticket. I am about to log back in and see if I got a reply.
You should go to the Duty Officer contact at Starfleet Academy and have him check your CXP allocation to correct any allocation issues from previous STO bugs. Your advancement to 'Diplomat' may have been messed, and this might correct the issue...
