Donation language only on donation checkout

Hello, I have a site that has a booking program in order to book a hall and the donation program for people to donate to the non-profit. When I have this plugin active and a customer makes a booking but no donation, The language on the checkout page reflects donation and not booking. How do I fix this. I don’t want it to say “Your Donation” or “Donor Details” when the customer is making a booking.

(Likewise, I don’t want the booking details to show when they are making a donation.)

Thank you,

Jason
