Need to change category site links from category/category/vidy-sporta/box/ to category/vidy-sporta/box/

Tried

RewriteEngine   on
RewriteBase     /
RewriteRule ^category/category/(.*)$ /category/$1 [R=301,L]

Does not help

Answer 1

RewriteRule ^category/category/(.*)/$ /category/$1/? [L,R=301]

give all htaccess and what specifically doesn't work

Answer 2

Tried

RewriteRule ^category/category/(.*)$ /category/$1 [R=301,L]

Your working rule is simply put it in the wrong place.
It must be placed at the beginning of .htaccess in order for it to work before RewriteRule . /index.php [L]
