Dear a7mad, removing text from a PDF is not an easy task as - text which might visually appear as a single item might consistent of individual parts within the PDF itself e.g. each character or groups of characters are place individually in different COSStrings - text might be drawn using graphics commands - text can appear within different parts of the PDF (e.g. the text might be content of a form field AND the annotation representing the form field visually) - you need to look up the encoding information to get form the characters in the PDF "string" to the ones you are looking for ….
If you can post a specific PDF to a public location and describe in detail which string should have been replaced which hasn't I will be able to tell you why that might have happened.
