Multiste htaccess 301 redirections with paramater in URL

Hi there, I need a little help with htaccess redirections on multisite instalation.

I need to redirect this:
“https://example.eu/en/index.php?dir=info&page=faq”
to
“https://exampleexample.eu/faq/”

This is my htaccess

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Redirect 301 /en/language-levels https://tracktest.eu/english-levels-cefr/
Redirect 301 /en/why-tracktest https://tracktest.eu
Redirect 301 /en/companies https://tracktest.eu/english-for-companies/

</IfModule>

# END WordPress

Redirect 301 works, but is not working with paramaers in URL. It redirects to random page with parameter “dir=info”.

One other problem

Redirect 301 https://example.eu/cz/about https://example.eu/cz/kontakt/

Redirects example.eu/cz/about to example.eu/contact

Please, can somebody help me?

Thank you!
