I see that you want the entire model to have the same solver configuration and so are trying to attach the 'Solver Configuration' block to multiple parts of the model. This is not needed as the 'Solver Configuration' model applies the configuration properties for the entire model. Multiple 'Solver Configuration' blocks are only needed if there are more than one topologically different models (two models that are not connected to each other). Here's the documentation link for the 'Solver Configuration' block for more information:
Hope this helps!
