Change in position of center of letters in ContentsReplace

Hi

When the characters are positioned at the center and I run ContentsReplace, the centered position is not kept and it slightly changes in position.

The result file that I have attached here shows that they are not positioned at the center but lean toward left, whereas they are positioned properly at the center in the source file.

I do not know why it happens.

Do you have any solution for this?
