What should I do if I can't change collision presets?

I’m working on a game for a uni project that is due in a couple of hours and I can’t change the collision preset on a couple of assets from Custom to OverlapDynamicObjects and now when ever I replay the level they don’t allow players to go through them and be teleported to another section of the map.https://youtu.be/4LuST8JuOfI

If you open the blueprint and change the collision value from there, it should allow you to change the preset.

It looks like the blueprint you placed is using whatever value you set in your blueprint as its default. You can use ‘Custom’ if you are changing the responses per instance but selecting another overarching preset should only happen in the blueprint.
