I suggested this edit that was rejected with the reason it didn't improve the quality of the post.

The suggested edit improved 3 problems with the post following consensus about editing guidelines:

1. Removed tagged keyword from title.
2. Corrected casing of tech names.
3. Removed salutations.

Each of the above is considered enough reason to edit a post, but on Super User correcting multiple issues with a post still leads to suggested edits being rejected.

Can someone explain why edit reviewing criteria on Super User doesn't follow the established guidelines of the network?
