tidy models stacks referencing non-existent column when predicting on new data

I am creating a Plumber API that returns predictions from a stacked ensemble model made with stacks. I am hitting an error when trying to create the prediction though. I have a column called customer_800_club that is used in the model workflow. When the new data to be predicted is used by the predict function, it is somehow called customer_800_club_X0. I have the following code to make my prediction:

my_pred <- predict(right_model, new_data = to_predict)

where right_model is of class: "linear_stack" "model_stack" "list"

I have gone through every step of my workflow and cannot find where the column name would be getting changed. Thanks!
