Hi Geoff,
As a quick test I imported a simple Lavastorm graph into Analyze:

and the script is being displayed in the Advanced tab as expected, so it's not a generic issue:

Can you try performing a hard refresh on the UI in your browser using <Ctrl> + F5 to see whether that rectifies the issue.
If that does not can you create a cut-down version of the graph containing just the problematic Sort node and a couple of sanitized data records in an upstream static data node, and attach that to this forum page.
Is the issue only happening for one specific graph or does this happen for all graphs / a new test graph?
Can you also confirm the version of Analyze you are using, the operating system and whether the Analyze instance is a Server or Desktop system
