On the vCenter > Cluster/Host > updates baseline tab is missing and only image tab is seen
vCenter 7.x
When the cluster is configured to use images at the time of creation or if the cluster is updated to use image, it is expected behaviour for the baseline option to be missing as we can use either baseline or images for updates but not both.
This is not an issue, if the cluster is configured to use images, it is expected to not the baseline option anymore
