Double integral problem

[Highdef]

Hello :-)

I am having trouble with a double integral on the HP Prime, that I believe I tried solving with a previous firmware (don't remember version), and now when I try it, the Prime returns:
"Error, Too many arguments: integrate"

I am doing this in CAS mode. Are there any settings than can cause this? See attached problem.

I am typing on the Prime: int(e^x^2,y,0,2*x,x,0,1)

Thanks.
