How would I create a smoother/less glitchier TweenPosition?

Below, I have provided a LocalScript that's a child of a gun. I have already defined "Gun". The parts that I have in bold (or astericks) is where the Tweening takes place. When the weapon's equipped, the three things tween into the screen as you can see, but when you unequip it and re-equip it too fast, some text doesn't make it up on time or it doesn't go in the right order. It looks glitchy. Also, in the ChildRemoved section, under the TweenPosition, it has a wait(). I did that to clear the text AFTER the Tween has finished but apparently it doesn't work. It may have something to do with the Override function in TweenPosition but I barely have any clue what that is. How can I change that as well?

Could anyone suggest a good way to fix and improve this to make Tweening more efficient?

I will greatly appreciate it. Thank you!
