Unable to enter Grand Prix Event. Todays fix didn't help

Am I missing something? A few days ago I accepted the quest to run the Grand Prix event with a character under level 50. I found that that was a mistake since you have to be level 50. I thought with the fix today for that problem it would solve my problem. However my level 37 still has the quest and cannot abandon it. BUT my higher level characters cannot run the event either now…still. I get message saying insufficient quest requirements. So…I can’t abandon the quest on my low level and I can’t do it on my highers since my 37 still has it.

I can’t help but feel this is shoddy coding unless I’m missing something. Meanwhile I’m STUCK and cannot run the event. A little frustrated here. HELP!!
