Print seem to be opposite

[R2D2Rodriguez]

I was printing an arm with a indentation on the upper left corner and it correct on the screen but it printed on the opposite side.
I also printed a robot with the eye on the left according to the file , but it also printed on the opposite side.

Can someone share some light ?
I was informed of on one of the axis been check off, but I couldn't find where in the program or why since it was printing ok before .
