Error Message "Non-Designable - Null Value of Critical Moment on Segment"

I am performing a design in RF‑/STEEL AISC for result combinations from RF‑/DYNAM Pro and get the error message "Not designable - Null value of the critical moment on the segment". What can I do?

Answer:

In this case, the only solution is to increase the limit value for special cases for bending in Details; for example, from 0.01 to 0.05 (see image). This way, correspondingly small moments are not taken into account.
