Managing custom metadata & custom metadata records via the Salesforce UI is tiedious at best, especially if the number of records is large.
Alternative - You can build UI using Flow or LWC but you will need to jump through a number of complex Apex hoops using Metadata.CustomMetadat & Metadata.DeployCallback to get the job done.
Best Path - Or you can pull the records into a CSV and use the sfdx-cli to prepare them to be pushed - easy as that
