Cluster Validation error - Update level warning

Hello
I have 2 server which will node for cluster (vrtx M640) . I performed cluster validation and all the time I received warnings that servers not running the same updates. It is strange because according to update history they have installed same software. Another thing is that one KB - 4462930 is missing on one of the server ( on other server was installed ). I tried download it and install manually but I reveiced message that this is not applicable on this computer. I checked and it seeams that on one server first was installed KB4462930 and than newest Adobe updates -KB4561600 and on this node all is ok, on second node first was installed KB4561600 (success) and then attempt to install KB4462930 (failure). I suspect that in this case newest KB contains 4561600 thats why I failed to install it (but I am not sure).
Anyway please help with this strange behavior during cluster validation, I need make cluster without any warning:)

Below I attached screnshot from server1, server2, cluster validation report:

Update mismatch warnings can happen if the nodes of the cluster were updated on different cycles. This can happen when one node gets updated with a particular patch but the other node was updated later and it applied a patch that superseded a patch that was applied to the other system. The warning is simply that - a warning. You can generally investigate the patches to find this.

The best way to avoid this is to perform a clean installation and full patch of each node before creating a cluster.

Agree with Tim.

We may check the nodes' patch level according to the warning, if we have confirmed the nodes are updated at the same level with the latest windows updates, we can ignore the warning,
