A couple of things:

I have added 1 of this person to the battle group in the game start schematic, but this yellow double appears too.

When selecting something with the cursor, there is a considerable offset between the cursor and the object. It also applies to combatants and placement highlights.

Painting grid cells will only affect an entire vertical column.

Thanks

The same combatant can be part of the group multiple times (each their own instance), so make sure you only join it to the group once.

The cursor is placed based on the combatant's game object position (and the cursor's settings, e.g. offset, targeting a child object, etc.). If your combatant prefabs e.g. have their origin position (their local X=0, Y=0, Z=0 position) somewhere else than the model/graphics, that'll cause such an offset.

As for painting grid cells - are you using 2D or 3D? When using 2D, make sure you've set up the project to use 2D mode for horizontal plane and raycast type (Game > Game Settings) as explaind in the 2D tutorials..

The project type is 3D.

Edit: Misunderstood what was meant
Alright, painting works right..

There does not seem to be another non-player person added.

Yeah, the setup seems correct.

Where is this UI displayed and how is it set up?

Namey

It is displayed in a Battle Menu (Clone) box.

So, as part of a target selection for something?
If the combatant isn't added twice to the player group - what are the target selection settings of the action displaying it twice? Maybe it targets All and you're fighting the same combatant?

The same Grid Deployment combatant selection as the Grid Tutorial was used.

Originally, the same combatant was being fought. It was changed, but the yellow double of the previous person was still there.

Update: I forgot there was this other plane above the plane I was using for the tilemap, and moving it down to the actual tilemap solved the other problems.

Hm, yeah - I guess I'll need a Unity test project with your setup to check out.

If you can send me one, you can reduce the size by deleting the Library folder from the project's folder. Zip it up, upload it somewhere (e.g. dropbox) and send me the link to contact@orkframework.com.
