Good day! 
 How to solve this warning? I already set the range of application in the load cases details, still no avail to fix this one. Thanks.

These warnings are reported, because the program is not able to generate wind load on some areas, as the geometry is too complex. I would recommend you to apply wind load for a group of members (certain areas) which are really exposed to wind. Create a group of members for each wall separately and then apply wind loads to each group (this can be done by using STAAD Editor only). Some more details on this can be found here (question #27): communities.bentley.com/.../staad-pro-load-generation-faq 
 An attached model could be used as an example, where I have created separate groups (WindX1 to WindX6) where wind load in X direction will act. I then applied wind load to those groups only (by using STAAD Editor). You would need to do the same for members exposed to wind load in Z direction and repeat the same task for each load case.
