Target Activity ID is available in Analytics dimension "Analytics for Target", but is not mapped in Target Activity > Experience

Hi all,

we have an active A/B Test in Target on one of our pages:

In Analytics dimension "Analytics for Target" this activity id is displayed with proper metrics:

But in Analytics dimension "Target Activity > Experience" this is not mapped to the names of experiences 

"ATAT-81" is the name of the activity in Target, which should be displayed. We were under the impression that this is mapped automatically. Is this a bug or is there anything we can do to reestablish the mapping?

Any feedback is highly appreciated.

Kind regards,

Tom
