Parameter (Data Page) changes are not saving in pxListView while implementing constellation UI in Theme cosmos

Trying to implement Configuring a Constellation table in a Section (Theme-Cosmos application)

As per document embedded pxListView in existing section and added application specific data page and saved changes. Opened the rule again and application specific data page disappeared and reverted to OOB worklist. Tried multiple times, logged off and logged in and even cleared cache but still same proble,

See attachment for more details. Is there anything we need to configure.

@kumms this seems like a bug, though I have seen this before with paramaterised datapages and constellation tables running from traditional UI. We are seeing the same in '25 version of Pega (alpha testing right now). Investigating further if this is a known issue/limitation with our Product Teams.

I would definitely raise a request on Pega Support to get it addressed. You may have to look at options removing the parameter (as an input at run time anyway).
