"show ip arp " will provide you the IP address mapping to MAC addresses whereas "show mac address-table" gives you from which switch port the MAC address is learning from & whether it is static or dynamically learn MAC address.
In your case why same MAC address learn via two different switch ports on two different vlan ?
Looks like your sever having multiple connections. I would physically inspect the server end & ensure how many cables connect back to network. In that way ensure which physical port it should learn in normal condition.
Then if you suspect other port is wrong (eg G1/0/25) see what is connected to G1/0/25 physically. trace it back to see where it end up with.
