Bot is unable to recognize the context

I have an issue where bot is unable to recognize the context throughout the dialog task
Scenario:
Dialog Task-Change Appointment
When bot enters into the Change Appointment Dialog Task
Bot Says----How can I help with your appointment
Customer says-----I need to change it
Bot is unable to refer it—>appointment and going to fallback task
The training utterances are 1)I need to change the appointment
2)Can i modify the appointment
So Here Appointment is not an entity to capture but within the dialog task it is unable to refer it—>Appointment

How can I make this work by taking the context into account?

Hello Hemanth,

Welcome to Kore.ai Community.
Could you please share reference screenshots of the configurations made on the bot and dialog tasks ?

That would help us to identify the issue and assist you accordingly.

Thank you,
