Got different version RHEL after installation and reboot

Hi All,

If anyone got this weird issue that RHEL version is different from what you installed?

Example:
I tried to install RHEL "workstation" version 7.7 with bootable usb and put installation source with our Red Hat satellite, but I got "server" version 7.5 after rebooting the PC.

It will be grateful if someone can provide guidance.

Regards

Gary
