Need Help with Stretching Texture in UMG

Hello, I have a texture in my UMG that is stretching (see image attached). I’ve set it to UI/Clamp and tried different compression settings. I also re-exported the PNG with a transparent border around it, as suggested in another thread I found here. Any suggestions on what to try next?
Thank you very much.

Maybe try increasing the size of the transparent border.
