Try deleting the command from the button and dragging the same command over from the IRDB. See if it corrects the issue. I was on a job this week with a 890 and the top two soft key buttons, when pressed, was triggering the opposite buttons command (including it highlighted the opposite button). In other words, pressing the top left soft key button would trigger the top right soft key button command. Deleting the commands and dragging over the correct commands fixed this. Actually, I deleted both buttons, not just commands. I copied another button, pasted it in those two soft key locations, and then dragged the correct command from the IRDB on top of those buttons. This fixed it.

This was only occurring on one device.
