 * Hello! I would like to report a bug found in compression level selection box 
   in media.
   When changing the compression level of any image in media details >
   dropdown list.eg. from Medium to High
 * The image thumbnail is being recreated and webp of the selected media will be
   deleted also. But then it will not be regenerated again.
 * My current workaround is using a custom plugin to add a regenerate webp link 
   in media list so that I can easily regenerate any missing webp. I suggest SG 
   speed optimizer to add the logic of the webp generation side by side with the
   thumbnail regeneration.

 * Hello [@simongcc](https://wordpress.org/support/users/simongcc/),
 * Changing your compression level will re-generate all existing images. In case,
   you would like to back up all original images, you should select the mentioned
   option in:
 * **Media > Image Compression > Edit**
 * Regards,
 * Vladimir
