@basabeo Those scans don't measure "muscle mass." They measure fat-free mass. Implementing cardio (or extra exercise in general), without a compensatory increase in carbohydrate intake, would probably lead to some glycogen depletion. This would also decrease the amount of water in your muscles. This would all show up as a decrease in lean mass on a body scan. Adding 30-minute walks is almost certainly not causing you to lose muscle.
