Contact Form 7 & Suspicious Query Strings Conflict & Fix Inside

I noticed that enabling Suspicious Query Strings rule in system tweaks conflicts with Contact form 7 and doesn’t allow it to run properly. To fix this I edited the following line in .htaccess

Find:
RewriteCond %{QUERY_STRING} ^.*(request|select|concat|insert|union|declare).* [NC]

Change it to:
RewriteCond %{QUERY_STRING} ^.*(select|concat|insert|union|declare).* [NC]

If you know why this is happening or if you have any better solution please share.
