I have got the Saudi PCC last week. The profession is not mentioned there in my PCC but it is mentioned in my wife's PCC.
The difference is that my fingerprints were taken by a machine (fingerprints scanner like the ones in airports), the form is electronic, my name and Iqama number is printed. The guy didn't type my profession or even date of birth. All blanks
My wife's fingerprints were taken manually (by ink stamp) on a manual form, names, profession, date of birth is handwritten on the form. It's clear that the ladies section doesn't have the machine. They do it manually.
For your info, I went to the main Eastern Province Police Head Office in Dammam (King Abdulaziz Street). The other (small) police offices won't have the machine and therefore, they will use the handwritten form. If you are based in the eastern province, then I recommend that go to the police headoffice. It took 6 days for me to get the report.
In anycase, as mentioned by 'destination canada', profession miss-matching won't affect the immigration process.
Best of luck.
