unexpected umap of analysis with Sketch and BPcells

[CampingOnSeabed]

Hi, I'm currently attempting to follow the tutorials and utilize BPcell and Sketch to prepare a reference dataset consisting of 100,000 cells. The subsequent steps involve running FindTransferAnchors(), TransferData(), and MapQuery() to map my single-cell RNA sequencing (scRNA-seq) data onto this reference dataset.
However, after completing all these operations and generating a UMAP plot, the outcome was not as anticipated. The cells from my dataset are positioned outside the area of the reference UMAP plot. Given that I had expected these cells to cluster closely with the "Medulla" region in the reference UMAP, I suspect there might be issues with how I've employed MapQuery() and Sketch. Unfortunately, I'm at a loss regarding the appropriate corrective measures to take.

Hi,
What was the solution for this @zskylarli ? I'm running FindTransferAnchors and MapQuery on sketched data as my query and also had weird mapping results. Referred to this issue https://github.com/satijalab/seurat/issues/9753 but the solution was not clear.
