You used the SlingStudio Console Save Project as Default feature to create a "default template," but now your new projects aren't being created with those default settings.
Did you recently reset your SlingStudio unit to its factory settings?
If so, then that's the cause: The Save Project as Default feature's saved settings are not retained if you reset your SlingStudio unit to its factory settings.
Note: This is true no matter which of the options you selected when you performed the factory reset operation on the SlingStudio unit.
Use the Save Project as Default feature once again to re-save the default settings that you want. Create a project with your preferred settings, and then re-save them as a default.
