AddThis Appended URL Tracker error

I have the URL tracker option enabled on one of our sites and jQuery keeps printing the following message in the console :
Uncaught Error: Syntax error, unrecognized expression: #.Wc4G056WbDf
at Function.fa.error (jquery.js?ver=1.12.4:2)
at fa.tokenize (jquery.js?ver=1.12.4:2)

at new a.fn.init (jquery-migrate.min.js?ver=1.4.1:2)
at n (jquery.js?ver=1.12.4:2)

How can this be resolved ?
