CodePudding user response：

This is the intended behaviour of the plugin WP Reset Pro.

It creates snapshots with names as yours:

• naming template for snapshot tables is {6_char_random_hex}{table_prefix_for_your_site}{original_table_name}

To delete snapshots, use the appropriate function:

If you do not need a specific snapshot on your WordPress site, you can quickly delete it:

• Open Tools -> WP Reset -> Snapshots
• Scroll down to the "User Created Snapshots" card
• Select a snapshot & open the "Action" menu
• Click "Delete snapshot"
• Confirm that you want to delete it by clicking the red button
