StorageType not maintained by filesystem BlobStore

The directory related methods on BlobStore are deprecated, so I am trying to update to the new directory-less scheme. However, when I do the following, 

Blob dirBlob = blobStore.blobBuilder("some/path/").type(StorageType.FOLDER).build();
blobStore.putBlob(containerName, dirBlob);

BlobMetadata fetchedMeta = blobStore.blobMetadata(containterName, "some/path/");
StorageType fetchedType = fetchedMeta.getType();

fetchedType (BLOB) does not match the type on dirBlob (FOLDER). 

One place this causes problems is when these directories appear as normal blobs when doing a BlobStore.list()
