Hello, I have the same issue. So I use SSH instead 
It must be a terminal implementation error. Partially fixed by setting Backspace = Ctrl + H in putty.
seems kernel 4.14 doesn’t have this issue.
Is this mainline openwrt (and changing only the kernelversion fixes it)? Why should changing backspace handling fix arrow keys
