A mean of 0 #1

Using the Artscore function gives awfully low mean or even a mean of 0 for the habitat of 7140. So i would like to know if i'm doing something wrong with my data, or it's something with the habitat type.

The species within the site are as following:

Something2 <- structure(list(latinsk_navn = c("Calamagrostis canescens", "Carex nigra var. nigra", "Carex rostrata", "Carex strigosa", "Cirsium palustre", "Comarum palustre", "Eleocharis palustris ssp. vulgaris", "Epilobium palustre", "Equisetum fluviatile", "Filipendula ulmaria", "Galium palustre ssp. palustre", "Glyceria maxima", "Hippuris vulgaris", "Holcus lanatus", "Juncus articulatus", "Juncus conglomeratus", "Juncus effusus", "Lotus pedunculatus var. pedunculatus", "Menyanthes trifoliata", "Phragmites australis", "Salix aurita"), Habitatskode = c("7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140", "7140")), row.names = c(NA, -21L), class = c("tbl_df", "tbl", "data.frame"))

This is probably the same problem with the average numbers as #2
