Design SLS (Area element)

Hello,

I have a problem calculating stresses in concrete slab elements using Task Desig SLS (Area element).
The calculation gives an error due to the punching calculation.
The punching calculation is not done in SLS, but in ULS, so this error is not clear to me.
When I enter Teddy, there are no CTRL SLS and NSTR commands.
How can I calculate stresses in concrete slab elements?
Thank you.

Your question has nothing to do with your problem description.
