How do I get rid of the extraneous code appearing in the product description as shown below.

New Zealand target="_blank" target="_blank" href=""New Zealand/a>/a>6 AUG 1975 Health First Day Cover with 4c Miniature Sheet MNH. Good condition althoughmini-sheetis a little wrinkled.

I looks like a category URL, But I have removed the category from this post and tried many other things.

I am using Market Press, (and have done for some time) on Word Press 4.
