problems with PDF Split by Text Content Case ID 544567 Case ID 544971

I have been using your software to split pdf by text content and it
worked like a charm previously.
But recently I am experiencing some problems trying to do the same as it
somehow spilts the PDF in different pages without following the text
content properly.
Attached are the screenshots of what I and trying to do to split PDF by text content. (There is no option to upload my PDF file to you).
Your assistance is much appreciated.
Regards,
Marcus
