If you update this field on the two projects seeing this behavior, this will prevent future tasks from being created with blank Project field information. These can be updated by simply adding the sub tree root field to the form and set 'Read only' in the dictionary to false. Then, you can set this field to the same as the Project number. Alternatively, you could run a script like: // Fill in lines 2 and 3 with sys_id of project record in the quotes. var gr = new GlideRecord('pm_project'); gr.get(''); gr.sub_tree_root = ''; gr.update(); The script above is simply an example of how this field can be updated. If you plan on using a script like this, please test in a sub-projection first. The other option of manually updating this field will work just the same. Updating the sub_tree_root field will prevent the empty project fields from occurring when future tasks are created for this project.
