What about eno2, you also have two IP addresses there and even in the same subnet, is this wanted or not? Can the second address of eno2 be found in the ifcfg file? Both eno2 and eno4 have "scope global secondary dynamic" with the second address and it doesn't seem to come from the base configuration.
