Both of those are identical to any generic Zwave hub. It isn't a Hubitat tool, it is one from Zwave itself. So if you want to blame someone, blame Silabs the owner of Zwave for that and many other Zwave issues.
A repair on an individual device tells that device to go out and look for better routes back to the hub. A full repair does the same for all devices. In theory, these are not necessary for Zwave plus.
That chart tells you whether a device sees the hub, and if the hub sees a device. I can't recall which axis is which, but the more blue you see, the better. Blue indicates devices are talking to each other. [2.2.4.xxx] Help understanding "Z-Wave Topology" map
