layer_stats();layers_correlation() could not found layers from Bio-ORACLE 2.2

[Data-Madman]

Hellow everyone,

I have some problems with sdmpredictors, the layers codes in Bio-ORACLE 2.2 are not found by the functions in the R package.
Like：
layers_correlation(c("BO22_curvelltmin_ss", "MS_bathy_5m"))

MS_bathy_5m
MS_bathy_5m 1
Warning message:
In layers_correlation(c("BO22_curvelltmin_ss", "MS_bathy_5m")) :
Following layercode(s) where not found: ['BO22_curvelltmin_ss']

Thanks

your Linxuan

It is also worth mentioning that Bio-ORACLE 2.2 layers code cannot be stacked in the load_layers function. is there a workaround for this?
Like：
env <- load_layers(layercodes)

Error in load_layers(layercodes) :
Rasterstack for zipped and non-zipped files not supported. Try rasterstack = FALSE

Thanks again

your Linxuan
