Two Artsdata place IDs linked to single Spektrix venues

[dlh28]

I accidentally linked both Tarragon Theatre (K2-6113) and Tarragon Theatre Mainspace (K2-6391) to spektrix-tarragontheatre's Tarragon Theatre. Would it be possible to unlink the building and just keep the performance hall?

I noticed a similar error with Abbotsford Arts Centre, where both Abbotsford Arts Centre (K2-5506) and Abbotsford Arts Centre Theatre (K2-6385) are linked to it.
