Problem with my ctrl, shift and alt keys

I have a problem with my control, shift, and alt keys because, for example, when I press my shift key and remove my finger from it, shift remains activated until I press another key and then it disables. Normally, these keys are set to uppercase only when your finger stays pressed on the shift key, but here, even if I take my finger off the shift key, it will wait for me to press another key to deactivate, which is not normal and it's becoming bothersome. The same goes for control (ctrl); if I press it and remove my finger, it will wait for me to press another key to deactivate, whereas it should only function when my finger is on it, and the same for alt.
Please let me know how to disable this option.
I have a Razer keyboard if that can help.

PS: For the record, I'm not talking about the caps lock key.
