Why does TT say my OLDER THAN 24 yr son, who is a FT student, is a qualifying dependent?

We are filing MFJ.  Son is 27 y/o and full time student.  He has no income so we provide 100% of his support.

 

He does not meet the age test, yet TT says he's a qualifying dependent.  Is this accurate?  Or a glitch in TT's software?
