Hi suanlian.
Thanks for letting us know about your issue.
For sharing buttons above and below content, you can hand select services by selecting the Select Your Own option under Services and then a service picker should show up on the page.
A service picker isn’t built in at this time for the sharing sidebar and the mobile sharing toolbar.
You can change the services in the Sharing Sidebar using our Smart Layers API. To do this, go to the Advanced Options tab within the plugin settings and look for “addthis.layers() initial paramater (json format)”:

Using our API, you can specify which services you’d like to appear:

You can obtain the service codes from here:

Thanks,
