T-beam philosophy in bridge problem with aqb in desi

I have a two-span prestressed bridge: the girders are modelled as beams and the deck as quadrilaterals. I used the T-beam philosophy to avoid overlapping stiffness in the longitudinal direction.
The calculation stops at the CSM Bridge Design Beam, where I calculated the DESI MAXI ETYP BEAM and shows the error: * No matching load cases for selected beam elements*.
Any idea why this is happening?

Ensure that your load cases are correctly assigned to the beam elements and that they match the load definitions expected by the CSM Bridge Design Beam module.
