Parameter 'activityNameFilter' of getLeadChanges does not work

[Anonymous]

Hi all,

When I set an array { "New Lead", "Change Data Value" } to parameter 'activityNameFilter', getLeadChanges() returns all Activity records including the two and all other types.
How it happens? Did I miss anything?

Thanks,
Biao

Hitting the same issue as well.  

Looks like Marketo has acknowledged that this is bug:

Can someone from Marketo confirm?
