 The reason the MD5 check exists is that, if we try to sync the highlights of different books, all sorts of strange things can (and will) happen.  
 But if we're absolutely sure that nothing has actually changed in the contents of the epub, then, there is a way to bypass the MD5 check.

 If there is an MD5 mismatch, you can right-click the erroneous sync path (13) and select "Ignore MD5" on the popup menu.  
 This will create an empty `ignore_md5` file next to the metadata file, and will allow sync to proceed.  
 Right-clicking again on this path, will give you the option to delete the `ignore_md5` file by un-checking the "Ignore MD5" option.
