Urgent: YIndent position is not accurate + Replace is not working correctly

Hi,

I am using Aspose.PDF for .Net on a Temp Developer license.

I am performing a search for word in a document and I need to know its correct X and Y coordinates.
 
The document is 612 x 792 dimensions.

The YIndents I received for desired word is offset by atleast 10 units away from the top margin.
How can I fix this or is this an expected behavior?

This is my output of the searched word.
