Is your second screenshot of a task created by this workflow, or the RITM? Typically tasks that get created by a workflow will be skipped if they have no or an invalid Assignment Group. You can see what a workflow is doing by clicking the Show Workflow Related Link at the bottom of the RITM form. This shows the currently executing or comlpeted workflow context for this specific RITM, so you can see which activities have been completed, and which are running. The Workflow Context Related Link may also be helpful for troubleshooting. It looks like you have custom fields added to sc_cat_item for Task short description and Task description, so the workflow Catalog Task activity(ies) must have a script to assign these values from these fields. In this script you can add workflow.info lines to find out what the script is doing, and the value of any variables. The results of these logs can be viewed on the Workflow Context from the Related Link, on the Logs tab.
