LifeProTip: Cannot expand anchor points? Check to make sure RectTransform is correct or not.

I cannot seem to drag the anchor points out anymore. Switching to Rect Tool doesn't show the 4 blue corner points. "What gives?", you may ask.

In the RectTransform, check to make sure if the values in the Left, Top, Right, or Bottom fields are not very close to each other.

In my case (GIF above), the Left and Right fields are very close, and they are 325.15 and 326.29 respectively. This causes the anchor points to not be able to expand out away...
