TBC:learn new skill,can't cast by bot

My game vision is TBC,now i found tow bugs:

First:  When i learn new skills which is in fight class, bot cannot cast the skills which learnd right now. after close the bot ,all it's ok.

Second:  when i creat fight class ,after use  development tools(click spell books), my skills appear. then learn new skills,click spell books again, the number of skills no changes.
