User-specific custom field not showing up in user overview

Yes, it’s me. Yet again…

I just created the first custom field for users in our RT. Yet,
Admin/Users/Modify.html does not show said field. I confirmed that the
block starting on line 212 with

% while (my $CF = $CFs->Next) {

is not even entered once. Data::Dumper on $CFs tells me that no custom
field is in %values of the current %user .

I did give myself all permissions on the field (I am admin anyway) and
am using RT 3.8.1.

Sending this one to -devel instead of -users as I suspect there is
something wrong on RT’s side, not mine.

Thanks,
Richard
