in addition to modifying the cinder.conf, you can also use the cinder command in place of the nova command.
If you run nova quota-update (tenant-id) --gigabytes=100000, you will see the quota updated in nova, but running cinder quota-show (tenant-id) will not reflect this.
running cinder quota-update (tenant-id) --gigabytes=100000 will also work.
horizon should probably use the cinder quota and not the nova quota in the UI so it's not misleading.
