Option1:
DTM - Go to *`Property`* > **[ Edit Tool]** > Link Tracking and disable "Keep URL Parameters"
Option 2:
DTM - Go to link tracking rule > use custom code in place of UI
Add following code in custom code with in rule
var linkName = _satelite.getVar("Link PathName") //scrape href and convert to pathname in data element.
s.tl(this,'o', linkName);
