TPO with a revoked date

My wife and I moved into our new home back in December. The rear edge of the garden features a natural Devon bank lined by approx. 16 trees. Now seems to be the right time to call on the services of our local tree surgeons to give our lovely trees a prune.



After reading a few days ago, I found information stating I should check with my council for the existence of any TPO's. The interactive map on our council website shows the below TPO, approximately over our back garden. However, the final detail of the TPO says "Date revoke 4/27/2006". So does this actually mean the TPO has been cancelled since this date, and that the listing is purely a historic entry?

I was not made aware of any TPO on our property (no such observation made by our solicitor back in November).

Unfortunately, I am unable to tell what all the tree are, but pretty sure none of them are Popular trees. I can only imagine these were removed/replaced years ago. All I can identify (so far), are Willow and Hazel behind the shed, and a large oak covered in ivy behind the palm. Not sure how to distinguish which may be Elm.

 

Thank you @Loofah. It may sound silly, but I'm new to this kind of terminology and I don't like to take legal things for granted.
