occurrence 'fields' param not returning fields as expected

[popovs]

Hello, I am trying to extract some data with the occurrence function, but it is not returning the expected fields.

E.g. -

tmp <- robis::occurrence(scientificname = "Raja miraletus",
                         fields = c("scientificName",
                                    "basisOfRecord",
                                    "decimalLatitude",
                                    "decimalLongitude",
                                    "bathymetry",
                                    "shoredistance",
                                    "sst",
                                    "sss")
                         )

will only return 5 fields:

> names(tmp)
[1] "basisOfRecord"    "decimalLatitude"  "decimalLongitude" "scientificName"   "id" 

Limiting the fields to just 'sst' or 'sss' returns only the id column:

tmp <- robis::occurrence(scientificname = "Raja miraletus",
                         fields = c("sst",
                                    "sss")
                         )

> names(tmp)
[1] "id" 

However, if I run the occurrence function with nothing specified in the 'fields' param, I get all 136 columns, including my other columns of interest (bathymetetry, sst, etc.).
