Selection filter appears to be applying inconsistently

While using the selection filter feature in WebKarma, I have noticed a few quirks that lead to incorrect behaviors:

  1. When modeling, once I apply the selection, it appears later operations sometimes undo the selection and rows that were excluded are no longer grayed out. Unfortunately, I neglected to check if this selection also fails to persist in JSON-LD or RDF outputs. Currently I work around this issue by applying the filter last in my set of operations.
  2. In batch mode, R2ML models that contain a selection filter do not apply that filter. This includes the RDF and JSON-LD outputs.
  3. The above issue also occurs when I apply the model to a freshly loaded dataset in WebKarma, even the dataset I originally mapped. However, once I made some additional changes in the history, the selection filter appears again.
