stko export tcl file does not work

I modeled in stko and then exported the tcl file, but the tcl file won't run in opensees, what's going on?

Hi, the warning means that you are trying to add single-point constraints to a node that already has some constraints assigned. For example, it could be where you assigned fixity for the boundary conditions. With the model, it is easier to debug your issue. So, please check the node and DOFs with the warnings shown in the figures that you attached. You can identify and remove where the double assignment of SP constraints occurs. Thank you.
