The problem is that your raster resolution is 560 meters and you have specified a moving window size of 100 meters. You can't have a window size smaller than the cell size. Moreover, for a local neighborhood analysis using moving windows, it only is meaningful if the window size is many times the cell size. Lastly, although you did not select any core area metrics, you have the edge depth set at a fixed depth of 4 meters, which again is way below the resolution of your landscape. It won't matter for the current model since you don't have core area metrics selected, but you should be aware that edge depths should be specified in multiples of the cell resolutions for it to make sense.

Thank you so much for helping out. I tried running the model as you had instructed with the moving window size many times the raster resolution. I have however only received the desired output for three of the metrices selected (Splitting Index, Contagion, Cohesion) . The rest of the output however is the same as before. I have tried increasing the window size up to 100 times my raster resolution, it did not work. Please tell me how I should proceed.
Thanks

I just ran your model and got all 8 outputs. I used a 5000 m window, but that shouldn't matter as long as it is several times the cell size. I wonder if you are not seeing the results because of how you are displaying the results. The values range from -999 to some positive number depending on the metric and to "see" the results in a map display (e.g., in ArcMap) you need to change the map symbology. Try that and let me know.
