htaccess fails to redirect when encounter whitespace - apache

Question

I am using htaccess for clean url. Which is working fine as long as the parameters doesn't carry whitespace. In which case it converts the space in %20 and I receive 404 error.
So basically the URL: http://localhost:8080/series/dynamics/admin/cleanURL/green%20apple
gives me 404 error. But URL: http://localhost:8080/series/dynamics/admin/cleanURL/greenapple works fine.
Also is there a way I can remove the directory details from the URL, I tried
RewriteRule ^series/dynamics/admin/cleanURL/(.*)$ /$1 [L,NC,R]
But doesn't work
htaccess
<IfModule mod_rewrite.c>
Options +MultiViews
Rewriteengine on
RewriteBase /series/dynamics/admin/cleanURL/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^series/dynamics/admin/cleanURL/(.*)$ /$1 [L,NC,R]
Rewriterule ^([a-zA-Z0-9]+)/?$ index.php?product=$1
RewriteRule ^(.*)(\s|%20)(.*)$ /$3-$4 [R=301,L,NE]
#rewrite group and subgroup e.g. http://.../value1/value2/ [L,NC,QSA]
Rewriterule ^([a-zA-Z0-9]+(.*)+)/([^/]+(.*)+)/?$ index.php?product=$1&subgroup=$2 [L,NC,QSA]
</IfModule>

You will need to add this rule in your site root .htaccess:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) series/dynamics/admin/cleanURL/$1 [L]
Then have these rules in /series/dynamics/admin/cleanURL/.htaccess:
Options +MultiViews
Rewriteengine on
RewriteBase /series/dynamics/admin/cleanURL/
RewriteCond %{THE_REQUEST} /series/dynamics/admin/cleanURL/(\S*)\s [NC]
RewriteRule ^ /%1 [L,R=302,NE]
RewriteRule ^([^\s\x20]*)[\s\x20]+(.*)$ $1-$2 [L,R=302,NE]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
Rewriterule ^(\w+)/?$ index.php?product=$1 [L,QSA]
#rewrite group and subgroup e.g. http://.../value1/value2/ [L,NC,QSA]
Rewriterule ^([a-zA-Z0-9]+(.*))/([^/]+(.*))/?$ index.php?product=$1&subgroup=$2 [L,NC,QSA]
