Looking at the json files, the experiment does the following changes to the minecraft:behavior.float_wander goal:

      "minecraft:behavior.float_wander": {
        "priority": 2,
-        "must_reach": true
+        "must_reach": true,
+        "random_reselect": true,
+        "float_duration": [ 2, 7 ]
      },

I am not sure that the json changes are what is causing this. It may be that while exposing more parameters for float_wander, an internal flag was also set to not allow the float_wander behavior to run at the same time as other behaviors. That would explain why ghasts are stopping to shoot, and move for only about 1 second between shots.
