Yes, this is a known ACC limitation on issues. ACC only supports pushpin position for TwoDVectorPushpin (3D models) in directly linkedDocuments only unlike BIM360 that supports both TwoDVectorPushpin (3D models) and TwoDRasterPushpin (2D sheets and views).

There is a roadmap to improve the ACC issues to match each feature in BIM360 over a time but for now this coordinates position is not supported for TwoDRasterPushpin models
