RawImage not update in editor

I load all images from Firebase storage, put it in RawImage texture. it display good in editor.

After that i delete one of them, and reload all rest images and display it again. it for shift images to left and should last one keep white (default texture).
that not work! all images load again but last RawImage that should contain default texture not render in editor (it changed in Inspactor)
