AutomaticSize property not working as expected?

Hello! I’m currently experiencing a problem with my UI. I am attempting to extend the Main frame when the text size increases.

Here is my explorer hierarchy, anything outlined in red has an AutomaticSize property with the value of XY.

As you can see, the frame size increases, though the arrow does not move, is this expected? How can it be fixed?

What is the position set to for that arrow?

The position is {0.76, 0},{0.1, 0}.
