Hello Oleg,
I tested without the other plugins and by changing the theme. The problem persisted.
The installed version is 3.8.4 but named 3.8.2.4 in woocommerce-brand.php
I went back to version 3.8.3 and the problem disappeared.
I suppose that the latest version contains the bug.
Can you see where the loop could come from?
Kind regards,
