When I entered my 1098T, the AOTC for one of my children disappeared.

My husband and I have three children in college that qualify for the AOTC. I am also taking classes to improve my job skills and received a 1098T. I entered all our financial information and then entered their 1098Ts and 1099Q. Each qualified for the AOTC. When I entered my 1098T into Turbo Tax, my refund was reduced by $2,500. Is this a glitch?
