For those we cannot and will not help. This is a fork which uses the name Armbian without permission and does not contribute to the core development process. Ask at their place for help.
For the leftover:
code {
font-family: Consolas,"courier new";
color: crimson;
background-color: rgba(0, 0, 0, 0.2);
padding: 2px;
font-size: 105%;
}
armbianmonitor -u would be a good start.
