You will probably find there is a slab (or another element) in a hidden layer that has a stronger building material than your beam.
So you can either delete that element if not needed, adjust the building material strengths for the beam and/or hidden element, or change the layer intersection number (in the layer settings) so the two layers have different numbers (therefore elements will not intersect).
