This is a great feature of Axe-Edit! But I think there might be a bug (v0.9.102), or maybe just plain ol' user error...?
I go to Settings > Load Config > Run Profiler, which seems to detect the new features in firmware v9.03 just fine. For example, when I add AMP1, I can see both "CAROLANNOD2" and "CITRUS RV50" as options in the Amp's "Effect List" drop-down. But if I attempt to select the new "CITRUS RV50" option, it instead selects "CAROLANNOD2" -- both in Axe-Edit and the Axe-FX. Ironically, I don't experience any issues selecting the new "BRIT JM45" option in the Tonestack Type drop-down.
