New Bug Encountered: Grouped Action brings me to fastTable Blank Screen

I have a Grouped Action with 3 Actions inside.

  1. “Go to another view within this App”: Open a new Form
  2. Data Change on another Table with confirmation message
  3. “Go to another view within this App”: Go to the Detail View

When I klick OK in the confirmation message, it will bring me to the Detail View.
When I klick NO in the confirmation message, it will bring me to a fastTable, which in fact is a Blank Screen.
