Some species lists don't filter a query correctly

[daxkellie]

We can use species_list_uid in galah_filter() to return only information for species and subspecies on a specific list. For example, here we can filter to species on the EPBC list.

library(galah)

# Filter to species on EPBC list
galah_call() |>
  filter(species_list_uid == "dr656") |>
  atlas_counts()
#> # A tibble: 1 × 1
#>     count
#>     <int>
#> 1 3525524

However, it doesn't seem to work for all lists. This list is a user list of all tree species and can be found on galah. Yet when used in filter() returns no results.

# List exists on ALA
search_all(lists, "dr31947") |>
  show_values()
#>  • Showing values for 'dr31947'.

Do lists have to be authoritative to work with filter()? Is this list structured differently so that filter() isn't matching results correctly?
