gerber 6x00 error message

 Hi All,

 i have another question. Using gerber 6x00 settings in V15.7, I am trying to output gerber. But one of my inner layer (negative film) has error. Please see attached image. I think the thermal pin of the hole is the error (because it portrudes outside the copper pour???). How can I remove the error in gerber without changing the thermal flash?

 Thank you,
