In the Flow contexts that you attached, you can click into the Create Task step, it should have Runtime Values that will give you the value of the Sys ID or Number of the record created. Ensure that both are actually created records and are different. If so, then you may have a field not being set correctly, such as Request Item, which is how tasks are related to the parent record, the RITM. If you create a new task record and don't set the Request Item field, you would have an orphan task, which you can confirm with those runtime values.
