SC Order Guide does not show Choose Options and Toggle buttons in Service Portal

Hi Team.

I created an Order Guide in my personal (PER) instance and it worked well in the Platform UI and Service Portal.  I created it in the DEV instance exactly as it is in the PER instance.  However, now when I test the DEV version Order Guide in Service Portal, I do not get the "Choose Options" section.  The catalog items are listed in a section named "Included Items" below the "Describe Needs" section.  There are also no toggle buttons for them.  The PER instance Order Guide shows the "Describe Needs", "Choose Options"  and "Summary" banner across the top and under Choose Options, the items are listed with toggle buttons.

Both instances are on the Paris version.

In trying to troubleshoot, I opened the Order Guide record and attempted to disable the "Show Include Toggle" option to see if by disabling and re-enabling it would resolve the issue. But, I cannot disable the option.  Every time I tried to uncheck the checkbox and Save the record, the box automatically reverted back to being checked.

Also, the DEV instance Order Guide record has the tab named "Included Items", but in the PER instance Order Guide, the tab is named "Rule base".

Any suggestions will be greatly appreciated.

Thank you.
