Warning in Staad Model in time history analysis

Dear Forum Members,

I'm doing Time History analysis. After run of model, i'm getting the below warnings,

    **WARNING: Time History analysis is being performed with the
               MASTER-SLAVE command. Forces applied at slave dof will be ignored.
               Revise these loads so they apply to the master node and add one or more
               moment components at the master, if appropriate.


 *WARNING* MASTER / SLAVE EQUATIONS ARE NOT PROPERLY CONSIDERED IN A TIME/STEADY SOLUTION.

Please help if possible.
