Difficulty with creating variable

I was creating a variable customer_data and putting the customer_churn CSV file in it. Surprisingly, the variable contains a new kind of data with different records and columns.

We need a reproducible example (reprex)

I simply used the simplest code:
customer_churn->customer_data

it did the trick, I was able to get customer_data (variable) with full features of original data, customer_churn
