PCG Spawning Meshes at different Heights

Hello all, I have a question. I am currently working on a project and have into an issue that I can’t figure out how to resolve. I am attempting to spawn a randomly selected group of static meshes (6-7 out of 30 different options) using a PCG. However, roughly half of the static meshes that I have spawn at a different height, leaving the doorways at the wrong heights and the player unable to move through. Does anyone know how to fix this? (I have attached pictures of the problems as well as some of the blueprints I am using for the PCG.)
