Cannot change texture format type, it is resetting to Default 8192

I import my sprites to Resources/Chapter 1/Level 4/Textures/layer1 folder. And it is Default format with 8192 size. When i am trying change format to some another, texture is resetting to Default format 8192. When I change folder (not Resources) all its ok. But i need use Resources folder.
I have 5.5.0f3 unity version. Before I build 3 levels without this problem. But now i have this problem.
And if i copy my old textures (for other 3 levels), problem is same.

Solved. I have enabled toogle on override format for other platform. But I don’t know how i get this enabled toogle. :slight_smile:
