Fehler in der .htaccess Datei?

Hallo liebe Shopware Community,

ich habe eine Frage bezüglich meiner .htaccess Datei - aus irgendeinem Grund funktionieren die 301 Weiterleitungen nicht. Mach ich da was falsch? Richtig platziert im Stammordner müsste die Datei sein, denn die Umleitung auf https klappt einwandfrei. Nur diese Weiterleitungen klappen nicht:

Redirect 301 /test/haartest/ https://www.mixmyshampoo.de/haartest
Redirect 301 /alle-kategorien/top-10-gefaehrliche-inhaltsstoffe-in-shampoos/ https://www.mixmyshampoo.de/top-10-gefaehrliche-inhaltsstoffe-in-shampoos 
Redirect 301 /alle-kategorien/indisches-haaroel-selber-machen/ https://www.mixmyshampoo.de/haaroel-aus-indien-selber-machen                
Redirect 301 /shampoo-gegen-spliss/ https://www.mixmyshampoo.de/shampoo-gegen-spliss-und-haarbruch                                                            

Anbei die ganze .htaccess:

<IfModule mod_rewrite.c>
RewriteEngine on

#RewriteBase /

# Https config for the backend
#RewriteCond %{HTTPS} !=on
#RewriteRule backend/(.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{SERVER_PORT} !^443$
RewriteRule (.*) https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
