Textract JSON Data Issue

I am using Textract's asynchronous functions StartDocumentAnalysis and GetDocumentAnalysis to detect signatures on a document using AWS SDK Python. The JSON data I receive is correct from GetDocumentAnalysis is correct for all test documents except for the test document(Declaration Finance.pdf)

Following is the issue:

1. The form has 4 signature blanks. However, the json data I receive does not put the signatures in "BlockType" : "SIGNATURES"
2. Sponsor signature blanks from the document are put in "BlockType" : "LINE"
3. Applicant signature blank from the document is put in "BlockType" : "WORD"
4. Attached is the test document and the JSON data file
