error with scrublet calls in Seurat metadata

[GreyRockIQ]

Hello
I am getting error with the code that you have given in 10k pbmc analysis in R for keeping scrublet calls in metadata
code given:
doublets <- read.table("../data/scrublet_calls.tsv",header = F,row.names = 1)
colnames(doublets) <- c("Doublet_score","Is_doublet")
srat <- AddMetaData(srat,doublets)
head(srat[[]])

Error: duplicate 'row.names' are not allowed

Any suggestions to correct this error?
Thanks
