When a model is run from its tool dialog box, the output of the model (Dissolved) will not be added to the ArcMap table of contents, even though Add To Display was checked for the output variable. The reason is that when a model is run from its tool dialog box, the Add To Display setting is ignored. To add the output to the display, you must make the output variable a model parameter.
