syncing a specific folder, LR always indicates there are five images to be synced, there are none

Using the latest version of LR on a PC.  When syncing a specific folder, LR always indicates there are five images to be synced, in addition to any images I know I have added to the folder.  If I sync this folder without adding any images LR still insists there are five images to be synced.  Should I maybe move all my images from this folder to a new folder, remove the "problem" folder and see how LR behaves when syncing the new folder?
