Hello Anas.
Thank you for contacting Hilti.
I am sorry but it's not clear what you need from the details that you have provided. I reviewed the design file you have attached and it seems to be a working design and I do not see the connection between the message you have attached and the design. The error message seems to be a result of attempting to design a connection which is only experiencing compression loads. Here the rebars are not sufficiently activated and therefore the software gives that error. That is my assumption without looking at the specific details.
Please provide more information if the above has not been helpful. If you would like you can leave your email and I will get in touch with you to discuss further.
Regards,
Amad Qureshi
