Profile theme not saving on user creation

[a-ok]

When I add a new user, even if the 'UIkit' theme is selected (by default), upon creating the user then logging in as said user the theme is the default theme. If I go to the profile, no options are selected. If I select 'UIkit' here and save it's all fine.

Any thoughts?

I'm on Processwire 3.0.123 but I've had this issue since using v3.

*UPDATE*

I actually just uninstalled the default theme but it's just the 'non' theme that it seems to use even though UIkit is selected on creation.

I've always had this same issue. Can confirm it happens on even previous versions.

Any thoughts? Even a manual fix for now (hook or otherwise?)

Bump? Still unsure of how best to fix this...

Have you tried setting the "defaultAdminTheme" config setting to the theme you want?

$config->defaultAdminTheme = 'AdminThemeReno'; // Or whichever theme you want users to have by default
