When you activate EGO Power the weapon you have is switched

Is it only me a bug that frequently used weapons change when EGO Power is activated?
Please check,

PS4 NA

Any time i press Y(while holding left bumper/L1.) or triangle in your case the gun will switch. I dont know if i press Y to fast or if its a bug. Also Ive had situations where I will auto change my loadout. Could be just me holding Y to long or pressing Y to much/fast. I do tend to spam or hold Y when activating skills do to me and lag.
