Serviceability & Strength Result Combine

Hello,

When analizing LOAD LIST ENV 1, 2 together, I have warning message as below ;

"  **WARNING- Deflection check of member #     XX will not be performed as DFF value not provided. "

(XX is member No. which was not input DFF parameter)

I input DFF parameter for beam member and didn't input DFF parameter for colum member.

then, above warning is occured at not input DFF parameter member.

Q1. Can I ignore this warning?

Q2. Did I input wrong syntax?
