My Favourites count not correct

Hi There everyone, not sure if anyone has experienced the same problem. But it seems that the my favourites count, as seen in the top menu when selected, doesn’t appear to correspond to the actual number of items saved in my favourites. For example at the moment I did have some favourites selected but they were all unselected however the count says that I have one favourite in the list i.e.) My Favourites (1) even though there are none.
Any Ideas.
Thanks
