\dt shows table but \d <table> says the table doesn't exist ?

[David Gauthier <dfgpostgres@xxxxxxxxx>]

psql (15.3, server 14.5) on linux

Someone else's DB which I've been asked to look at.

\dt gives many tables, here are just 3...

 public | some_idIds                                       | table | cron_user

 public | WarningIds                                       | table | cron_user

 public | cpf_inv_driverIds                                | table | cron_user

but \d public.some_idIds gives..

Did not find any relation named "public.some_idIds".

Soooooo... what am I missing ?
owner is "cron_user".  \dt shows cron_user is the owner of the table.
