Data Layers seem to break Runtime PCG Hierarchical Generation features

Steps to Reproduce
To reproduce:

  1. Create a PCG system using HiGen with two or more grid sizes and perform some sampling to generate points.
    1. Set the Default Generation size to Unbounded
    2. In the PCG graph, send data from a higher grid size to a lower grid size to perform an operation (such as a Distance or Difference). (Fig. 1)[Image Removed]
  2. Place the PCG into a World Partition Map with Streaming Enabled as a PCG Volume and adjust accordingly to project on a suitable surface.
    1. Set the Generation Mode to be Runtime (Fig. 2)[Image Removed]
  3. Add the PCG generating actor to a Data Layer (Runtime, Editor or Private).
  4. Regenerate

Expected result:

The larger grid size passes the point data to the smaller grid graph and the Distance to the paints is calculated.

Actual Result:

The points in each grid generate but do not sample from other grids. Only Unbounded data is sampled by smaller Grids. (Fig. 2 see above)

Removing the PCGVolume from the Data Layer restores functionality.
