Hello, sorry to hear about the trouble you are facing. In general, we do not recommend using multiple layer list widgets. You will get better performance and a better user experience with 1-2 layer list widget(s). Here are a couple other threads on the subject:

Google translate to Spanish (if that helps?)

Hola, lamento escuchar sobre los problemas que enfrenta. En general, no recomendamos usar widgets de lista de capas múltiples. Obtendrá un mejor rendimiento y una mejor experiencia de usuario con los widgets de lista de 1-2 capas. Arriba hay un par de otros hilos sobre el tema.
