Los bordes de los autómatas tikz se superponen.

Los bordes de los autómatas tikz se superponen.

Tengo dos estados colocados horizontalmente y necesito conectarlos, es decir, A -> B y A <- B, ¿cómo puedo colocar los bordes de manera que no se superpongan y mi diagrama no se convierta en A <-> B? pero en cambio se ve que uno puede navegar entre sí y poder colocar el mensaje de entrada arriba y abajo.

 (APPEND_COL) edge[???] node[anchor=east,above,xshift=+3.0em]{delete column} (DELETE_COL)
 (DELETE_COL) edge[???] node[anchor=east,above,xshift=+3.0em]{append column} (APPEND_COL)

¿He intentado configurar ??? arriba, abajo, doblar a la izquierda = 20, doblar a la derecha = 20 pero ninguno de estos produce el comportamiento deseado ...

ACTUALIZACIÓN: ok, aquí el código completo, y otra cosa, ¿cómo puedo hacer que los bucles de izquierda y derecha no sean tan grandes?

Como las líneas que las conectan tienen direcciones opuestas, tendrás que usar bend left=<value>para ambas líneas, no bend leftpara una y bend rightpara la otra:
