rectangle Box coordinates are incorrect

Dear support,

I am using attached document (test_esign.pdf) to extract some custom rectangle boxes for a regex text. Notice the text in page 3 that looks like this: {{t:s;r:y;o:"Insured";}}
I noticed that the LLX, LLY,URX,URY appear to be huge like 2498/2101/3316/2207 when they are expected to be under 1000 number.

1. Is this a bug?
2. Why are the coordinates of the textfragment so high and
3. what is a solution for me to solve this and obtain correct coordinates?

-        Rectangle    {2498.736,2101.496,3316.08,2207.096}    Aspose.Pdf.Rectangle
        Height    105.59999999999991    double
        IsEmpty    false    bool
        IsPoint    false    bool
        IsTrivial    false    bool
        LLX    2498.736    double
        LLY    2101.496    double
        URX    3316.08    double
        URY    2207.096    double
        Width    817.344    double

Thank you,
