Lightroom CC: Continually syncing 10 photos

my lightroom cc has been continually syncing 10 photos for the past 3 weeks.  The blue circle, top right of the page has been revolving for that period of time.   1 of my 60 albums has had the blue cycle, which normally revolves when images is added to a album, on stop for that period of time, all the images, 45 in number, inside that album have the full round ticked disc showing that the images have been synced.    All the other albums show the full blue ticked disc.
  I have tried deleting that album and then reimporting them from an external hard drive, this did not solve the problem
