As per information raliability may have issue related to Physical connection or duplex mismatch.

the config you show in the post, and the config on screenshot show differrent interfaces.

what is this device, what code it running ?

main physical interface has reliability fixed 255 and no drops, only sub vlan interface has that drops

clear the counters again, check what % that drops? what is the utilization of the port ?
