I dont think you will have any problems, it is just because AU know little about stepper motors, and have not put the correct info on the datasheet.
Run it in series first at 3A and then try in parallel at 6A, and monitor the temp.

I did notice the discrepancies, but I have low expectations of rhyme or reason when looking at stepper specs. May be okay, may be lucky they were cheap

I'll let you know
