That spritesheet is not formatted for use in MZ, unless you have a plugin. And plugins cannot change what you see in the editor or how you select characters.
The name may also be wrong - ! means to align the character with the grid, rather than a few pixels higher, and is normally used for inanimate objects like doors and chests, but not for actors or NPCs. $ means the spritesheet is only meant to have one character rather than 8. Without a $, it is expecting 12 columns and 8 rows of sprites.
Whatever plugin you're using will tell you how your image should be named, but if you have something other than 3x4 with a $ in the name, or 12x8 with no $ in the name, it is just not going to look right in the editor.
