Doing it with ASCII:

  procedure ClearScreen is
  begin
    Text_IO.Put (Item => ASCII.ESC);
    Text_IO.Put (Item => "[2J");
  end ClearScreen;

(copied from screen.adb, (C) Michael Feldman)

You're using a static object. So either copy the needed lines to a
new one or use dynamic handling of your array. This is not something
you can do if you're new to Ada (mixed-cased spelling!).

You should better blank your old data and/or resort your array-data.
Why do you need to shrink an array? This sounds very unusual.
