How to set up crib to toddler bed conversion link?

I have a crib cloned from one of the base game convertible cribs, and when I go in game to "convert to toddler bed", it claims it's converted but nothing happens (I get a notification saying it was converted). I can still put the mobile on it and use it as normal for infants. I double checked from the crib it was cloned from and it's supposed to just pop into being a toddler bed when the action is done. 

I looked through the warehouse and tuning but couldn't find anywhere to link a toddler bed mesh/texture, or link an asset for it to convert to. I see it has different tuning than a non-convertible crib, but I'm not sure where exactly the conversion link is handled.

Does anyone know how to do this?
