Because you have no connection between the VBoxManage command on the host and the Guest Additions installed on the guest (if any), as you can guess from the output of VBoxManage guestproperty enumerate node-01 command, which contains only host properties.

In general, all three VirtualBox components (VirtualBox, Extension Pack, Guest Additions) must have the exact same version number (5.2.18 in your case, at least for two of the three components). The exact same version also means being from the same provider (only one of Oracle, Ubuntu, CentOS, Vagrant). Additionally, the Oracle forums are for the Oracle versions only, because we cannot know the subtle differences the other providers introduce in their VirtualBox variants.
