Unable to update glibc to the latest version

We use Katello/Satellite 6 to manage our repos/pkgs and subscribe our servers to it. In the Katello Web UI it says that glibc-2.12-1.212.el6.x86_64 and glibc-common-2.12-1.212.el6.x86_64 is an applicable update on the system, I'll then click to update and it'll say successful.. however nothing happens and Katello still shows me that it's an applicable update. If I ssh to the server itself and try and do a yum install glibc-2.12-1.212.el6.x86_64 it says no package found. This is on a CentOS 6.10 box. We have some other packages such as nscd which rely on the latest glibc as a dependency as well so I'm just super curious why this is happening. repo id repo name status company_repos_centos6_extras centos6_extras 43 company_repos_centos6_os centos6_os 6,695+18 company_repos_centos6_updates centos6_updates 305+54 company_repos_epel6 epel6 12,515 company_repos_katello_centos6 katello_centos6 4 base CentOS-6 - Base 6,695+18 dgoodwin-subscription-manager Copr repo for subscription-manager owned by dgoodwin 8+2 epel Extra Packages for Enterprise Linux 6 - x86_64 12,517 extras CentOS-6 - Extras 46 foreman-client Foreman client 1.20 4 group_qpid-qpid Copr repo for qpid owned by @qpid 25+3 logstashforwarder Lostash Forwarder official repo 1 lynis Lynis YUM repo 51 company company Repository for CentOS 6 - x86_64 636 company company RPM Repository for CentOS 6 - noarch 37 pulp Pulp Community Release 21 subscription-manager Subscription manager repository from Candlepin 8+2 update CentOS-6 - Updates 329+54 repolist: 39,940 Uploading Enabled Repositories Report company_repos_centos6_os and base repos definitely have glibc-2.12-1.212.el6.x86_64 in there. As requested in the comments, my /etc/yum.conf contains a repo that has exclude=glibc-* kernel-* and actually doing a yum update doesn't work.
