Error with rescaling

[camcecc]

Hi @ricardo-bion, I have a problem with rescaling... can you help me? I'm not so good in R, so maybe there's something I'm missing :)

genus <- read.delim("per_radar-chart.txt")
genus_radar <- genus %>%
  mutate_each(funs(rescale), -Group) %>%
  select(1:5) %>%
  ggradar()

What I get is a fancy radar plot with only values 0 or 100%, not even a middle one... while my data file is:
