Tabula-py Not readng the full data of file

Question

I was trying to read table from a PDF file using the tabula read_pdf() method. But it is not reading complete table. It is missing out on some row of table. I was trying the below given code:

tables = tabula.read_pdf(f,
                         stream=True,
                         pages="all",
                         silent=False,
                         multiple_tables=True,
                         password=pas,
                         pandas_options={'header': None}
                        )
df = pd.DataFrame()
df = pd.concat([c for c in tables]).drop_duplicates()
df = df.replace(r'^\s*$', np.nan, regex=True)
df = df[df.isnull().sum(axis=1) < df.shape[1] - 2].reset_index(drop=True)

This was the output while running the above code :

And the actual data from PDF file
