Text only shows on Scene, but not in Game window.

Hi guys, i have a really basic(?) problem.
Possibly it is because something Im missing.

I have a basic puzzle game where the player clicks the chars, makes words and the correct word shows on screen. It all works for now except the fact the words only shown in the scene, but not in the game preview. Im using TMP for nearly all of the texts in the game and everything except them works just fine.

Any ideas?

Thanks.

Level selection, all TMP and all dynamic.

Empty game screen. All of the time this stays the same.

After writing a correct word. This is the scene view, game screen is still empty.

I made prefabs letter “A” and tried again. Shows all.

Fixed it by making a new prefab, still don’t know why it was not working.

Anything special about the previous prefab?

Was this prefab initially created in some earlier version of Unity? If so which one?

What version of TMP are you using?

I deleted the old one, but i was looking for something different between them and I could not found one.

They are both created on the same version; 2017.4.24f1

I assume the latest one, It has not been a week before I downloaded the TMP.
