Print box smaller than it should be

[alanaxis 0]

I have a Anycubic Mega X printer with a print area of 300 x 300 x 305. I also have an stl file of a rectangle that is 10 x 2 x 276.  When I load the stl file in Cura, the rectangle is larger than the print space.  I've set the values in the configuration but am still unable to open the stl file in the allotted space. Are there other configurations I should be checking?     The print space is stuck at 150x150x150

I don't see a delete option, the problem was with the stl file
