I'm running a smart campaign to score web page access of anonymous lead, and found the problem as follows.
1. By web form input, an anonymous lead is merged to an existing lead (data from business card).
2. Lead's score becomes null.
=> maybe existing lead's score is prior than anonymous's? But existing lead never have score in this case because it's from business card.
Please see the following lead's activity log on April 9th.
Could you please advice how to avoid the problem?
I found the similar case, just FYI.
