page.search_for return extra height

[ashifaliclientpoint]

Hello
I am using pymypdf(1.19.6) to search string from a pdf file. And doing redaction. But it returning extra height in compare of original pdf file. And also removing the string which overlapped by this string.
Please help me for this strange issue.
I am also attaching the original file and converted file.
DRAFT_Executive.pdf
highlighted_file.pdf
