scMerlin No sitemap on RT-AC68U running Merlin 386.5_2 and scMerlin v2.4.0

[loopy1234]

Any idea why the sitemap does not load? I see the user1.asp as expected, but user2.asp just shows:
"This page shows a dynamically generated sitemap of the router WebUI. Provided by scMerlin.
Show page URLs? [ ]" with a checkbox that will not stay checked.

Note the device is running in "Repeater Mode" which I know disables some menus, so perhaps related to that.

The following is all I see in the logs:
