Maximun number of bot responses reached? Config parameter setting?

I encountered interesting issue. In testing phase bot worked well, except in one button which should take it back to previous question. It worked in other places, so I investigated what so special in this and found that there are too many? bot responses/utterances. Is there parameter in config which affect this. Or is it something else?

Here is where it does’t work, both should go back to intent /ABC751
