Sorry, I could not visit your pictures provided, but is your processor like http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20II%20X4%20840%20-%20HDX840WFK42GM.html ?
Your CPU (if it's the Athlon not the Phenom) is based on an iteration of the Bulldozer modular design (steamroller), so while it technically has 4 integer cores those cores are paired together in 2 modules which share a front and back end and a single FPU (even though that FPU is technically 2 FMA units).
Since this is the case windows reports the CPU as having 2 hyperthreaded cores able to run 4 integer threads, this is normal expected behavior and nothing is wrong.
