GEOquery::getGEO("GSE21032") pheno data mix up

When using GEOquery to download data fro GSE21032 the columns in the phenotype data is a combination of different information.

Below is an example of a column with both Gleason grade and tumor type in the same column. I am hoping someone could point me in a direction of either fixing the issue or a new way of downloading the phenotype data without these errors.

gse <- GEOquery::getGEO("GSE21032", GSEMatrix = TRUE)

unique(gse[[2]]@phenoData@data$characteristics_ch1.4)

Thanks!
