Missing blueprint function name

I wrote a function in my main HUD widget recently and as I added inputs to it, the function name disappeared and so I tried recreating it and the same thing happened again. I can still connect to it, but when I look for it, it has the name “BlueprintFunctionNodeSpawner_9426” How do I fix this? I’m using Unreal Engine version 4.22.2-6574378+++UE4+Release-4.22
