Well, grabbed a ED23, checked that it was correct on 2.9.3, and flashed forward to 2.9.4. Still shows correctly on Dashboard, System Info, and I/O Map. Grabbed the 'malfunctioning' ER that I kept in case I needed to reproduce, powered it up, and it was also showing correctly in all three places, despite still being on 2.9.4. Never even got the chance to go back to 2.9.3 and then back to 2.9.4. No idea what happened. [shrug]
