Why is my open level will open all level in a map?

I make a portal on “ThirdPersonExampleMap” and portal will open “PortalMap”.
But it open all level I have(contain all object on map).
Where’s wrong?

Protal_BP

ThirdPersonExampleMap and PortalMap in same folder

my project setting.

Can you collaborate more on But it open all level I have(contain all object on map) ?

I make a video for this question.
Maybe can let me solve this problem.

hm… your video is breaking up and it is hard to see what is going on… So, you open a portal map, and what happens after that?

All the objects of all the map appear in an overlapping form

level_door_and_light

ThirdPersonExampleMap

Main

PortalMap

after open level PortalMap

Could it be that on your portal map you added other maps (in levels tab)? Can you just play in Portal map? does it look all right?

I fix this with other post thanks help.
