Unity - Null Reference Exception Error when trying to generate Lists with an image and TMPro text

Question

On the project that I am working, I have a screen that has a list of "star system" that will eventuyally be clickable. The system should be spawning as a list with names, details and an image. If I force the amount of systems to spawn, They do so correctly, however, once I add the 'for' loop to tie the details in form the inspector, I am getting the following error. Also note that even though I have 4 items added on to the list, only two spawn and none of the input details are shown on the images. I have a feeling that the TextMeshPro system is causing the issue, as the example i am working off of from a tutorial is using an older version of unity and not TMP. Also note that the Destroy(mapSelectorTemplate); is not destroying the GameObject inside the Unity Editor as it should be.
