How should I Stop a Drawer with Linear Physics Constrain Limit from Moving Backwards?

I am trying to follow a tutorial from Ryan Layley to make working drawers with physics constraints (Unreal Engine 4 Tutorial - Physics-Based Interactions Part 4: Drawers - YouTube). The drawers move fine in the forwards direction, but they go too far back. His solution was to use “Set Constraint Reference Position”. It works well for him, and it sounds good, but for some reason it does absolutely nothing when I try. I have been changing parameters and doing just about anything I can to switch things up, but no matter what this node appears to do nothing for me. Can anybody tell me what I am doing wrong or offer any suggestions? I would appreciate any help pointing me in the right direction!

Here is my constraints setup on my drawers:

Here is the “fix” for backwards sliding, which doesn’t work for me for some reason:

This is what my model is doing, note the drawers going backwards:
