I have a message when I carry out the calculations from design> steel members design -options> calculations, and the message is the following:
Wall thickness of 1to10 12to16 members is less than 3 mm. The members will be calculated according ! to EN 1993-1-1 guidelines. However, it is recommended to analyze thin-walled sections according to the EN 1993-1-3 code.
and the image attached below will clarify more about what is happening:
And my file with this message as below:

, or you can download a file from the attached file below
How can I handle this message and carry out the calculations without encountering it in the file?
I believe there is a conflict with the design code, but I do not know where it is!, and I need to maintain the current thickness that I am using.
