This really doesn't sound like normal behaviour for a 4i4, certainly it's not something I've heard of before. If it is still under the 3 year warranty, I would contact the retailer you purchased from and have that swapped out.
For context, the nature of the various LED colours is simply because they are RGB LED's. By default they adhere to the Green/Amber/Red setup for signal (with red obviously be clipping), but it is possible to change these from within Focusrite Control, either for aesthetic purposes, or (as we designed it) for accessibility purposes (colour blindness etc).
Glad that you're getting on well with the Clarett, while the Scarlett's are excellent, the Clarett's are somewhat of a step-up when it comes to the audio-spec and some features.
Many thanks
