Believe you would "Resolve metric differences between the peers to calculate the valid K-value" They have already been configured and do not match as the log message shows K-value mismatch.

[help_desk]

The log states a K-value mismatch. K-values determine how EIGRP calculates the metric, but the metric itself is not the cause of the mismatch. To resolve the issue, we must explicitly configure the K-values to match on both routers. "Resolving metric differences" means modifying bandwidth, delay, load, or reliability to match. This does not solve a K-value mismatch. Even if both routers had identical interface metrics, they still wouldn't form an adjacency unless their K-values were identical.
