The reason for the warning message is - you have specified both member truss and member release command to the same member. You need to remove member truss command from your model. Partial moment release (with 1% fixity) at both end is sufficient to declare a member as truss.
Also you should rectify the following in your model--
There are still few floor groups which are not closed. For example, consider group B1 which is closed in three sides. So program is unable to generate floor load on this group.
You need to change the structure from STAAD PLANE to STAAD SPACE. Your model is not in a plane and there are also out of plane loads assigned on this structure.
