Views Slideshow content pane with argument will not display

I had the following issue with Views Slideshow and Panels. I was able to work around it which I'll describe after.

I have two content types: Client and Screenshot. Screenshot has an image field and a Node Reference to a Client. My goal was to create a panel page with a slide show of the Screenshot image fields in one of the panes. Initially I used the jCarousel module which worked, but I decided I wanted to use Views Slideshow, which is where I ran into the issue.

1. Views: I defined a view whose default display takes 1 argument, the NID of a Client. Filters are published nodes of type Screenshot. Fields is just the image field.
2. Views: I created a "Content pane" display and set the Style settings: Style = jCarousel. View Preview looked fine.
3. Views: I created a "Content pane" display and set the Style settings: Style = Slideshow. View Preview looked fine.
4. Panels: I created a flexible layout panel page:
   • Basic: Path = clients/%node
   • Argument = %node, Position in Path = 1, Context Assigned = Node: ID
5. The odd behavior came when I added the Content pane views to my panel pane:
   • jCarousel - If I added the jCarousel Content pane view, I would get a Settings popup in Panels that had the label "NID of the Client" and a dropdown with "Node: ID" as well as Finish and Cancel buttons. The jCarousel view would display fine on my panel page.
   • Slideshow - If I added the Slideshow Content pane view, I would get a Settings popup in Panels that was missing the label and dropdown. It only had the Finish and Cancel buttons. The Slideshow view would not display on my panel page. I did a view source and saw that the slideshow scripts were being included but there was no slideshow content

I did a number of things to see if the issue was with my Slideshow view: I created a block displays and page displays and they both worked fine.

I did finally try something that did get a Slideshow view to display in my panel, but this is a workaround: I cloned the jCarousel view display (because it worked in panels), I changed its Style to Slideshow and saved it. When I added that Slideshow view to my panel pane, I got the Settings popup that had the label "NID of the Client" and a dropdown with "Node: ID" as expected and this cloned and modified Slideshow view displayed correctly.

Due to the workaround I'm guessing that this is a panels issue, though it is possible it is a Views Slideshow issue but I thought I'd start here.

Because my workaround worked, this is not urgent for me, but I thought others should know about this.
Thanks,
