Hi,
Thank you, the images are okay.
1. There is no option to do that, but it is possible to achieve it via a configuration + custom code combo. First, change this option to above 0.
Then, add this custom code to the functions.php in your theme/child theme directory (copy from line 3 only!). Before editing, please make sure to have a full site back-up just in case!
2. I see what you need now. Well, this is more related to your database collation, which is by default case and accent insensitive in WordPress. This is not something I recommend to change.
There is an option on the plugin back-end, on the Compatibility Settings -> Query compatibiltiy panel, which will try to enforce that. It may not work though, and it may cause some performance setbacks. First try enabling this option, then this one. If none works, then try combined as well.
