Hey there, I’m not able to reproduce the issue even on meta’s staff categories nor on the theme component itself.
I think there might be some other issue happening.
Can you check with this data explorer query?
SELECT
c.locale AS cat_locale,
cl.locale AS loc_locale,
c.name AS cat_name,
cl.name AS loc_name,
c.description AS cat_description,
cl.description AS loc_description
FROM categories c
LEFT JOIN category_localizations cl
ON cl.category_id = c.id
WHERE c.read_restricted = TRUE
ORDER BY c.id, cl.locale
Another thing, are you on latest core and latest theme component versions?
