Child Anim Blueprint not listing every state

So I have what might be a bit of a complicated anim graph with nested state machines. Anim Blueprint works fine, but when I create a child blueprint, the Anim Graph Overrides are missing many of the entries. At first I thought it might be because many of my nested states were named the same - for example, I have three weapon states, and in each of those states are chained state machines to handle each gun barrel firing, so in those the states were named the same. However, I renamed them to give them unique names and they’re simply not showing up in the child anim graph.

Child class - missing override entries

k, poked around with it some more, found out it has something to do with copying and pasting the state machines. When I rebuild them from scratch they show up. Kind of a pain in the butt, but they show up.
