Bulk-delete not working as expected

[Archana]

I am trying to perform bulk-delete operation on a container.

Request looks something like this

{method=DELETE, endpoint=http://x.x.x.x:8091/v1/AUTH_62cdd842bcf44023b987196add34951e?bulk-delete, headers={Accept=[application/json], X-Auth-Token=[5c94641e6a4146f1a9857d6892206bbb]}, payload=[content=true, contentMetadata=[cacheControl=null, contentDisposition=null, contentEncoding=null, contentLanguage=null, contentLength=41, contentMD5=null, contentType=text/plain, expires=null], written=false, isSensitive=false]}

http://x.x.x.x:8091/v1/AUTH_62cdd842bcf44023b987196add34951e?bulk-delete

For Non MPU uploads, bulk-delete works fine. But in case of bulk-delete on multipart uploaded files, only the manifest file get removed, the segments remains.
