problem of deduplication

[crazysummerW]

Hello,
I'm having an issue when using sambamba 1.0.0 to deduplicate paired-end sequencing BAM files in NGS data.
After deduplication, the resulting BAM file contains reads that are completely identical, with exactly the same ID and detailed information. This is causing problems in my structural variation (SV) analysis.

What could be the reason for this, and is there a way to resolve it? I would like the deduplicated BAM file to have unique read IDs.

Information of reads before deduplication:
`samtools view sample.sorted.bam chrY|grep E100074100L1C005R0181713731
