How does one remove Wondershare's PDFelement watermark from OCR.space files?

Using OCR.space trial software, I get a second watermark from Wondershare PDFelement. So even if I bought the software, I would not likely be able to use it as Wondershare would want money as well, to unlock the bloatware that I inadvertently installed using their trial software. I have deleted all the Wondershare files I can find on my Mac, to no avail. Can anyone provide information to help me remove Wondershare’s PDFelement software? Note, the watermark below did not appear on the same file processed on a different computer, so Wondershare has corrupted my OS.

This is an issue with your local Mac, or? Not related to the OCR API, so nothing they can do.
