Do you use the Samsung Messages stock app or an alternative messaging app @neigh ?
Do all the themes you download and then apply have this effect or is it just this theme you've chosen ?
Does the theme information show that it themes out the messages app.
Try removing the theme and then re applying it as it may have been a glitch.
If so then contact the developer of the theme as they maybe able to help.

The advice I offer is my own and does not represent Samsung’s position.
