Column name being duplicated in recipe

[norhther]

This is the piece of code i'm having troubles with:

pump_recipe <- recipe(status_group ~ ., data = data) %>%
  step_impute_median(all_numeric_predictors()) %>%
  step_impute_knn(all_nominal_predictors()) %>%
  step_dummy(all_nominal_predictors()) %>%
  step_normalize(all_numeric_predictors())

prepared_rec <- prep(pump_recipe)

The error:

Error:
! Column name `funder_W.D...I.` must not be duplicated.
Use .name_repair to specify repair.
Caused by error in `stop_vctrs()`:
! Names must be unique.
x These names are duplicated:
  * "funder_W.D...I." at locations 1807 and 1808.
Backtrace:

So basically it seems like the step_dummy step is doing something strange, and creating a duplicated column here. I don't know why this is happening. This is the data I'm working with:
