Cannot load generate

I am designing building in STAAD.pro. I want to apply the dead load of the first-floor slab as a floor load in STAAD. But, While applying the floor load, Staad showed the error, "CAN NOT CREATE THE FLOOR LOAD FOR Y RANGE" in some parts. And In Live load, I have to give 20m in Maximum Y-Range instead of 5m so that load can apply and then again change 20 to 5m and it works. But when I again open my file it shows an error again then again I have to do this process. I have attached my staad model too. If you can help me, I will grateful.
