Backup/restore didn't restore VPN tunnel & other items

I have a Mikrotik HAP ac lite device running v3.25.2.0 that I tested the backup/restore on. There were numerous settings that didn't seem to restore. I have no way of knowing if these settings were backed up but then didn't restore correctly, or if they are items not included in the backup. One item I specifically know didn't get restored was a VPN tunnel. As this is important in the operation of the node this is a pretty big concern. Other items not restored were the time settings and location settings.

Can anybody shed any light on this subject?
