Solution:
There is an issue in Amasty_ShopbySeo extension, that affect all url with length equal 4.
You need to edit file in Amasty_ShopbySeo extension:
app/code/Amasty/ShopbySeo/Helper/Url.php

and change removeCategorySuffix method, from

public function removeCategorySuffix($url)
    {
        $suffix = $this->scopeConfig->getValue('catalog/seo/category_url_suffix');
        if (strlen($suffix)) {
            $p = strrpos($url, $suffix);
            if ($p == strlen($url) - strlen($suffix)) {
                $url = substr($url, 0, $p);
            }
        }
        return $url;
    }

to

public function removeCategorySuffix($url)
    {
        $suffix = $this->scopeConfig->getValue('catalog/seo/category_url_suffix');
        if (strlen($suffix)) {
            $p = strrpos($url, $suffix);
            if (!$p) {
                return $url;
            }
            if ($p == strlen($url) - strlen($suffix)) {
                $url = substr($url, 0, $p);
            }
        }
        return $url;
    }
