Answer: Yes, this is normal for Spirea japnica "Neon Flash". The individual flowers usually do not last more than a short time. Then they fade and eventually turn brown. You can trim them off by lightly shearing the plant, this will help it look tidier. If well watered (soil should be damp like a wrung out sponge, not saturated/sopping wet and not dried out) and healthy, the shrub should rebloom again later in the summer. Each year in very early spring, cut the shrub back to remove winter damaged stems; very early spring is also the time to shape it and control its size.
