Hello. You may have locked the beam reinforcements in the Beam reinforced concrete dialog. Unlock and reanalyze. The "Without Pile" option in the beam settings can be defined separately for each beam. You may have selected this setting on a single beam. In this case, only the beam whose settings have been changed does not use pile. In 3D, select all beams and enter their settings and select this option for all beams. Exit the dialog by pressing OK. Analyze again. If the problem persists, add your project.
