Error 4820 Fixed boundary condition in SPC 2 is not supported for linear static analysis.

Hi I am doing some topology optimisation on a 3D engine pylon and I have a problem when applying the boundary and load conditions on as it is saying that the boundary conditions does not support for linear static analysis. This is based on the following image.  The fixation represents the boundary conditions and the circle shaped hanging position is weight of GE90 engine and the triangle shaped hanging position is the thrust of GE90 engine. Can anyone please help trying to prevent error 4820 when trying to optimise this engine pylon. The link for my attempt to optimise the engine pylon is shown below.
