Check your toggled powers. Some click powers have effects that can be toggled in Mids. Also make sure you didn't add any extra enhancement like the Miracle +Rec. Anything that increases your max Endurance will also increase your recovery speed, so check accolades as well. Finally, I believe Musculature Alpha increases Endurance Modifications so that could affect it as well.
If it's anything actually wrong with the code (possibly but I doubt it) I can't help you there lol.
