This looks like ghosting or other flare caused by a reflection off the back of a lens element or filter. Flat filters are often the most obvious offenders.

If you are using a UV filter for "protection"¹, remove the filter. If you are using a graduated ND filter or a polarizer, you must weigh the benefits of the filter versus the benefit of not having a reflection.

¹ For a thorough look at the disadvantages/advantages of using UV filters for "protection," please see this answer to is uv filter a must?
