I have the same problem ("E" appearing as a softkey in various Activities or Device configurations). I emailed support describing the "E" softkey in one of my Activities. They sent me email saying they fixed and for me to update my remote (Harmony 520). I updated the remote and sure enough the "E" is gone now. Thanx Support... but they didn't tell me what they did. Later I discovered the same "E" softkey showing up in a couple Devices. Once again I emailed Support but this time they have asked me to call in to resolve the problem. I will do that when I have time. menawhile I was wndering if you had resolved your problem with the "E" softkey and if so, what is the process/steps to do so?
