Routing remove or add "/"

I see only when we change ADVANCED SEARCH configuration in the fields.

Edit .htaccess

#Add "/"
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ /$1/ [L,R=301]
#Or
RewriteCond %{REQUEST_URI} (.*/[^/.]+)($|\?)
RewriteRule .* %1/ [R,L,QSA]

#Remove "/"
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^(.+)/$
RewriteRule ^(.+)/$ /$1 [R=301,L]

This is pretty nice will try it.
