Height of object higher then the gantry height? (55mm) then it will not print one-at-a-time.

Also make sure the parts are plenty far apart. Also look at the "machine settings" and make sure all the offsets (top,left,right,bottom,gantry) agree with your printer. Also if you look in "slice view" mode and you look at the bottom layer and it is in one-at-a-time mode you will see only the first print on the first layer and the second print will be at layer 100 or whatever depending on how tall the first part is.

So you can test all this without actually printing anything.
