Unable to configure DSE from Opscenter - datastax-enterprise

Question

I am trying to configure DSE on newly configured centos 7 VM but I am getting error Attempting to configure dse-full 5.1.0, but found a different version installed. Upgrades and downgrades aren't supported." (opscd-pool-4) I am not able to understand why getting this error when the machine is completely new, even I haven't run any DSE command.
ERROR: Received error from node event-subtype="MeldError" job-id="a38724e1-2139-45f5-9266-079638c2ca2e" name="cassandra-5" ssh-management-address="192.168.159.175" node-id="dafe635a-6e98-4ae6-b0ea-6afa0da51731" event-type="error" message="Attempting to configure dse-full 5.1.0, but found a different version installed.

I am using Opscentre to configure Node.
Here you go detailed log of LCM

Updated Answer
I was able to sync up with Ranjeet offline and found that the logs posted above were the result of configure jobs, which require that DSE is already installed. When running install jobs, things proceeded as expected.
There were also some issues with newly supported platforms and platform checks working in confusing ways, but none of that is reflected in the logs for the original post in this question.
Original Answer
OpsCenter/LCM engineer here, I work on the provisioning features.
"Attempting to configure dse-full 5.1.0, but found a different version installed. Upgrades and downgrades aren't supported." The meaning of the error message seems pretty clear. You're asking OpsCenter/LCM to install/configure DSE 5.1.0. Are you positive that you don't have a different version already installed?
On apt-based target machines, you can check what version of DSE is install with 'dpkg -l dse-full'
On yum-based target machines, you can check what version of DSE is installed with 'yum info dse-full'
If you're really trying to install DSE 5.1.0, but a different version is already present on your nodes, you'll have to upgrade/downgrade outside OpsCenter LCM and can the resume managing configs with LCM after the desired version is installed. See http://docs.datastax.com/en/upgrade/doc/upgrade/datastax_enterprise/upgrdDSE.html
If you're attempting to install some other version (which matches what's already installed), then you'll have to clone your config profile and set the correct DSE version when you create the new CP. See: https://support.datastax.com/hc/en-us/articles/212267063-Lifecycle-Manager-Cloning-Configuration-Profiles
If you believe the error from OpsCenter/LCM is mistaken, and that you don't really have a different version of DSE installed on the target nodes, then we'll need more log snippets from LCM with the events leading up to the error, and information about how you confirmed the DSE version on all nodes.
