  1. You have two times the same source define once with a port mentioned once without. Generally for NFS you should not use a port. Remove the source definition with the port.
        <source>
            <name>FireCuda 520</name>
            <path pathversion="1">smb://192.168.88.254/FireCuda 520</path>
            <allowsharing>true</allowsharing>
        </source>

        <source>
            <name>FireCuda 520</name>
            <path pathversion="1">nfs://192.168.88.254:2049/Volumes/FireCuda 520/</path>
            <allowsharing>true</allowsharing>
        </source>
