Multiple events linked to Incorrect artist URI

[GaryMan1968]

Describe the issue
I was importing Burnstick events with K-IDs into Footlight from the "Events potentially with Indigenous agents" query results. I noticed that the performer value was not being successfully imported into Footlight. Examining these events in Artsdata, I noticed that the K-ID for the performer linked to these events was incorrect. The correct URI is K2-5090, not K25-090

To Reproduce
Steps to reproduce the behavior:

1. Go to Burnstick event
2. Click on performer value
3. See events connected to this URI under Derived Statements
4. Compare this URI with correct Burnstick URI

Expected behavior
If the performer URI for these events were correct, we would expect that these events would already be captured by our Indigenous Performances Calendar query.

EDIT: On further inspection, I believe this issue was caused by an incorrect sameAs triple for Burnstick in the ATC external graph:
