DESeq2 rlog output some genes all zero value.

Question

[MatthewP]

Hello, here is normalized counts and rlog values from same dds for one gene as an example.
counts(dds, normalized=TRUE)

$grep ENSG00000285390 NormalizedReadCounts.csv
ENSG00000285390,93974,ATP5IF1,ATP synthase inhibitory factor subunit 1 [Source:HGNC Symbol;Acc:HGNC:871],0,152.9196357348574,0,0,140.25796849320326,0,0,0,0,0,0,0,0,0,0,0,0,137.84888273256348,0,0,0

assay(rlog(dds, blind = FALSE))

$grep ENSG00000285390 RlogNotBlind.csv

assay(rlog(dds), blind = TRUE) $grep ENSG00000285390 RlogBlind.csv

Why blind = FALSE comes out all zero value?
