object is see-though after adding blueprint actor effect

[Marii_Yoshida (rei_001)]

Very new to adding blueprint actors, so I may just be making a simple mistake-
I was following this tutorial -https://www.youtube.com/watch?v=gfwfJQJ1Ui8&t=185s&ab_channel=GameMakerDhaka

basically - making a light effect attached to an static mesh on a blueprint actor. You can see the lighting effect is see thorough behind the dress form,

but when i click on it (and also the object itself, it is not see though - I want it to be opaque like this even when I do not click on it

Here is my blueprint-

Here is my material -

Thank you!
