ESXi 6.5 - vSphere Distributed Switch VLAN Trunked and MTU Supported Status warnings

After downloading, staging and applying patches to the first ESXi host in a vSphere 6.5 host cluster, the host, after exiting Maintenance Mode, showed 2 triggered alarms:
vSphere Distributed Switch VLAN trunked status
vSphere Distributed Switch MTU supported status

Upon further review of vDS settings and details, selecting vDS --> Monitor Tab --> Heath Tab, there was a warning of 10 issues (started at 12, but apparently the 'Out of sync' issue was resolved): 'Unsupported VLAN' and 'MTU Mismatch' for each of the 5 hosts. When selected each host, the panel below shows 4 of 6 vmnics as "unsupported" but there are VMs running on this host that don not seem to have any connectivity issues (at the moment).  How do I resolve this? We are currently running a vDS of 5.5 (we have not upgraded yet and I didn't notice until after the patching was completed), although the vCenter (VCSA) and ESXi hosts are at 6.5.0. This is in a production environment and I would need to correct this as soon as possible so I may continue with the patching to address a critical vulnerability.  Any help is appreciated.
