When installing a package via TMC UI the selected cluster for package installation is not showing up when the cluster group is not selected.
A different cluster will show up for package installation.
Tanzu Mission Control - Self Managed 1.4.2
This is a defect of the Tanzu Mission Control user interface caused by a caching problem.
Workaround: Select cluster group" in "Cluster Group Filter (optional)" first and then the cluster name in "Available packages for cluster" for the package installation.
Engineering is working on a fix.
Fix will be in a future version.
