confused about filing in multiple states and getting proper out of state tax credit

my son is  PA. resident/full time student in MA. 

made money in both Ca. and MA last year. the PA. return is only taking the tax credit from the higher earning job in Ca. and ignoring the tax paid from the MA. job?  he is getting refunds from both CA. and MA. 

I would think TT Deluxe would also see the MA> tax paid and combine out of state taxes paid for a bigger credit.

PA. also has local EIT and is asking to report the out of state income from the PA40 GL and out of state tax paid.

I fear TT is limiting the tax credit for the local EIT as well.

 

I dont know how to fix this issue.  thanks everyone.
