BQ24630EVM: ISET1 voltage unable to be changed

Part Number: BQ24630EVM
Other Parts Discussed in Thread: BQ24630, BQ24610

I have two evaluation boards for the BQ24630 and both have the same issue that I cannot understand.

The eval boards come set up with ISET1 = 0.6 V corresponding to 3 A of charge current.  I would like to set the charge current to 1 A by adjusting the ISET1 voltage to 0.2 V.  However, when I change the resistors R11 and R12 to 100k and 6.49k, or even 511k and 33k (both combinations should give about 0.2 V on ISET1) I see ISET1 still at about 0.6 V and when I start charging a battery, the charge current is about 1.5 A.  I don't understand how changing out these resistors does not adjust the voltage correctly on either evaluation board.  It's like the BQ24630 is supplying current out of the ISET1 pin or something else strange is happening.

Are there any other possibilities as to what could be happening?  Thank you.
