To begin with, that it just so happened that PrestaShop, usually the end of the page without the slash.
So check your modules and make sure that they did the page without the slash at the end.

If you still have to do with slash a specific static page, so to avoid duplicates, add .htaccess line: 301-wow (full) redirect to this page:
Redirect 301 /module /module/
and that this entry is not lost when you update the cache in file ../ваш_сайт/classes/Tools.php
locate the entry: fwrite($write_fd, "\n\n");(or similar, about 2500 line).
Below it insert:
fwrite($write_fd, "Redirect 301 /module /module/\n");

Came up with a more global and correct option using mod_rewrite:
in file ../ваш_сайт/classes/Tools.php
find the entry:
fwrite($write_fd, 'RewriteRule ^api/(.*)$ %{ENV:REWRITEBASE}webservice/dispatcher.php?url=$1 [QSA,L]'."\n\n");

after it insert:
fwrite($write_fd, "RewriteCond %{REQUEST_URI} ^/module$\n");
fwrite($write_fd, "RewriteRule .+ ".(Configuration::get('PS_SSL_ENABLED') ? 'https://' : 'http://')."".$domain."/module/ [R=301,L]\n\n");

Updated .htaccess distortion switch "Optimizing Apache" in the "Advanced settings >> Performance"
