What act test to submit

Those are essay scores which are not relevant, her reading score would be on the same scale as other sections (up to 36).

Has she already applied and sent/reported the ACT scores? I ask because perhaps she should apply test optional, again, we don’t have enough info to know. What does her GC recommend?

Yes, if she has good mid-term grades she should communicate those in her interview. Her GC can also send the mid-term grades to admissions.

Good luck.
