UI Image not appear in mac / ios

Hello,

I have a problem on UI Image.

when I play test on Unity Editor(Window), or Android, It works correctly.

but it's not working in unity editor (mac) / iOS.

this is screenshot on test playing in window/android.

these are screenshots from each window/mac.

And this is inspector view in test playing (editor on mac).

Left image is origin of sprite (in project view).

and right image is inspector view of panel.

Although sprite is in source image, it's not appeared (and preview show no image).

I wonder why this happen.

If you don't know though, if you have any idea, please leave a comment. it's very helpful for me. thank you
