Bug-Report: Cast inside loop not affects all objects

Hello there,

i got some weird thing i cant explain myself.
i created a new actor blueprint added 6 static mesh components under the “DefaultSceneRoot”

the settings are standard
that is only what i’m doing but it does it only for 3 of 6:

adding a delay node after the begin play does not fix it.

my unreal version is 5.3.2-29314046
seams like a bug for me, but sometimes is only missinformation.

EDIT:

Same problem on 5.5.0 newest version
