Text Widget Arcade Code Inside List Widget Showing Inconsistent and Weird Behavior Since October Update

[bkaplan1]

I had Arcade code displaying formatted text in a Text Widget that sat inside a List widget.  It worked early last week but now experiencing lots of weird behavior.  Was it every supposed to work?  Did the October update mess things up.

Please someone help!.  

I've experimented with several things and I hope this is clear.  I first present my issues in a simple Exp Builder App and then show you my real App I'm trying to build.  In both cases, there is some weird behavior.  I hope it can be solved easily.

 In the following App there are two lists and one map.

In this test Exp Builder app, this is showing in edit mode and it looks fine.

The text is coming from a Text Widget inside the List Widget where both the list and text are connected to the same datasource.  I created Arcade code to display the text I want by the two steps shown in this screen shot..  

The code for the column on the left is 

// Final formatted text

  return ("Day " + $feature.nDay + " - " + $feature.BaseCity + " - " + $feature.Desc_);

Right column

return $feature.nDay; and text in box is T-

I know you don't need Arcade here but I think it is needed for more complicated discussed further below.

So it looks okay in edit mode, and in Live View, but in Preview it looks okay for a split second then reverts to the following with the name of the Arcade code appearing.

And then when I publish, everything looks fine for an instant and then I get the following

In the more complicated Experience Builder App, I have a similar page with a list and a map.  I duplicated the page.  

Now I'm getting this in edit mode where only the second row is showing the Arcade name

In preview or published mode I get the following name of the Arcade code:

But get this. I duplicated the page.  If I go the first page, I get the screen shot above.  But then if I go to the duplicated page in Published mode it appears fine.

If I open the Exp Builder app in a browser and go to the duplicated page, I get the Arcade code name and when I go to the original page the text appears okay.

I dearly hope someone can explain this.   It was working fine before the Oct update.
