Cloned models not colliding/interacting with items?

Hi everyone, I'm currently making a game in which the player can select a map (which is just a model that I put in ReplicatedStorage) and it will get cloned into their plot. The problem I'm having is that any items like rockets from launchers or bombs seem to just go through the model and don't interact with it at all, while players can't walk through it. When the model is in the workspace, players can blow it up, but when cloned, they cannot. Does anyone know how to fix this issue? Thank you.
