UK work visa

Dear expat.com
I am a practicing doctor. I had gone to Oman for a job with Ministry of health in August 2017. But on arrival in oman I decided not to join appointment. Therefore I returned to India within a week but was unable to cancel my employment visa(valid for 2 years) as nobody asked me to do any such formalities. However I have emailed Oman Hospital about being unable to join back. I have now have a UK work permit for Jersey, channel Islands hospital. i will be therefore applying for UK visa soon. Will a uncancelled Oman Visa pose any problems for UK work visa?

I think it's best to cancel it.
