Marquee selection auto-selects all blueprint actors as well

So I have this issue that occurs when I try to select an area of static meshes. Every time I drag out a marquee selection in the side-view, the tool auto-selects all the level blueprint actors. This is an unwanted effect in my situation, and I am not aware of how to turn it off as it is very heavily interfering with my level design work. I’d appreciate any feedback or knowledge on this issue.

Thank you!
