I'd suggest setting the minimum IR duration for each of your digit IR codes to .01 seconds to see if that does the trick. Inserting a delay action before or after the sending of the given IR code does not always suffice. I have some channel macros for instance which don't need delay actions at all, but do require that the minimum IR duration for each IR code be set to .01 seconds. I have others that don't need the minimum IR duration adjusted, but do require a .10 second delay action inserted before or after the sending of each IR code. Just takes some trial and error in some cases to get it nailed down per the particular component you are working with.
