hello, testing solvers, something strange happens with fsolve

WITH CSOLVE COMMAND:
csolve((X^2-2*X) = -3,X) [ENTER])returns
{1+√2*i,1-√2*i}

approx(csolve({X+Y=2,X*Y=3},{X,Y})) [ENTER])returns
{[1.+1.41421356237*i,1.-1.41421356237*i],[1.-1.41421356237*i,1.+1.41421356237*i]}

WITH FSOLVE COMMAND:
fsolve({x+y = 2, x*y = 3},{x,y},{0,1-i}) [ENTER])returns
{1.+1.41421356237*i,1.-1.41421356237*i}

NOW WITH DIALOG BOX of FSOLVE ([APP]SOLVE [ENTER])
✓ E1: X+Y=2
✓ E2: X*Y=3
[NUM][v (down)] 1+i[ENTER]) show Error Input Invalid. Why?
