Hello everyone, I am combining three different datasets together, and on the process to normalize the data, I encounter following errors. I am not sure how to solve the issue. I hope you guys could offer some suggestions.

data.anchors_new <- FindIntegrationAnchors(object.list = object.list_new, normalization.method = "SCT", +                                            anchor.features = integrate.features, verbose = FALSE)

Warning message:
In CheckDuplicateCellNames(object.list = object.list) :
  Some cell names are duplicated across objects provided. Renaming to enforce unique cell names.

data.combined_new <- IntegrateData(anchorset = data.anchors_new, normalization.method = "SCT", verbose = FALSE)
