SSSD always caches, that's how it works, the data is always first stored
into the cache by the sssd_be process and then read by sssd_nss.
The way you'd debug this is to enable debug level for the nss and domain
sections and also perhaps run ldbsearch for this GID, something like:
ldbsearch -H /var/lib/sss/db/cache_$domain.ldb
'(&(objectclass=group)(gid=891504278))'
