After loading a saved routine, nothing shows on the HEP Editor page and I can't deliver the HEP.

If you hover your mouse over a saved routine name, an no small preview images appear to show you what exercises are in the routine and then you load it...you will not be able to deliver the HEP. Please do not load these routines. Please re-create and save a new routine with a different name to quickly use it in the future.
