I have 2 carts, one with income and one with expense. Income data is showing in firebase and in my app. Expense data in only visible in firebase, not in app. There is some code: ExpenseFragment:

I can see expense data in firebase database, but not in app. Don't focus on difference in "totalamount" fragment, because expense data should be visible without this.
Thank you for any help.
