afrilandcover object can not be plotted

[avallecam]

Dear afrilearndata team,

The afrilandcover object can not be plotted using the raster::plot() function.

pacman::p_load_gh("afrimapr/afrilearndata")
pacman::p_load(raster)

# the issue is here:
raster::plot(afrilandcover)
#> Error in .local(.Object, ...):

# as a comparison, this works:
raster::plot(afripop2020)

when I try to plot it using the ggplot2 and stars packages I obtain the following output:

pacman::p_load(ggplot2)
pacman::p_load_gh("afrimapr/afrilearndata")
pacman::p_load(stars)

ggplot() +
  geom_stars(data = st_as_stars(afrilandcover))

I hope this reprex be useful to identify a possible issue.
