After the calculation start, RF-/FRAME-JOINT Pro appears in the "1.2 Cross-Sections" window and shows the following error message: "The value is out of the allowed range. Design value: 0.00 - Min. value: 3.00". However, I cannot detect a mistake.
Columns consist of a parametrized I-section (welded section). To use such a cross-section in RF-/FRAME-JOINT Pro, it is necessary to enter the web weld thickness as well. On the one hand, the weld in tension area is designed in RF-/FRAME-JOINT Pro; on the other hand, your thickness is also used in the calculation of effective lengths of the T-stub.
