Some achivements are not working

[threshold10]

Master of Destruction - tried twice a battle against 1600 men against lord Raymond, killed every one of them with spells, used only 3 sage heroes, for some reason only got high as 944/100
Historian - spent more then 7 hours, at the chronicles window and nothing
Born diplomat - again more then 50 interactions with other rulers at the diplomacy screen and nothing.

I have gotten "Master of Destruction", but the rest I have been unable to get either. I have done over 50 diplomatic actions interactions and still nothing. I have also disabled my screen saver and left my computer on overnight and have not gotten Historian.

We need clarification on what exactly needs to be done for Historian and Born Diplomat.

Can someone confirm if these achievements are bugged or what exactly needs to be done to get these?

Some response from Paradox about this would be appreciated.
