In this erratum, we correct some issues in the reported results of Lambda, Xi, and Omega production in the original article. Specifically,
1: Lambda pT spectra and integrated yields were not corrected for feed-down from the Xi decays.
2: In some figures, incorrect Xi and Omega integrated yields were used.
3: In some figures, there were mistakes in calculating ratios between particles.

For the record, updated and original data tables are uploaded at
