Shader distorts 2d texture when selected in "Quad" preview"

Hello! This might be a dumb question, but I seem to be having trouble adding a shader to my 2d sprite. Whenever I use the “Quad” option in the main preview window, the sprite gets distorted like this:

(the right is the distorted sprite in-game, while the other one on the left is what its suppose to look like)

I am trying to make a simple wind shader (I am following Unity’s tutorial here: Noise and Textures in Shader Graph! | 2D Shader Basics - YouTube)

This kept happening to me whenever I use 2d sprites. Can someone help me here? Thanks!

(This is the “Main Preview Window” that I was referring to:)

Nvm i found the solution: you have to connect the Sample Texture 2D (the one that contains the actual picture) alpha to the Main Stack’s alpha channel
