World composition problem(character placement)

When i create world in world composition, i use tiles, upload heightmaps. When level is created, i’ve placed a character using starter content ThirdpersonBP on the created terrain (screenshot 1

). But when i hit play button, playable character appears in air(very high), while created one(mine) is still standing on the ground (screenshot 2

) Please, i am asking for help!

Update: i still have problem. I have tried via Player start, but when i press play, my character do not want to spawn on player start. He spawns on 0,0,0 coordinates. Then, i tried to open starter content and to play with player start there, but it still did not work

Did you ever find a solution? I’m having this same problem.
