How to change the Posts widget of the WPBakery Page Builder plugin?

Question

WooCommerce

Activated the Posts widget of the Uncode WPBakery Page Builder plugin on the page! In its settings, I specified a selection by category, activated pagination. The widget displays products from the specified category. The trouble is that the widget generates the address of links to spreads with products without a slash at the end of the page address

1) <a class="page-numbers" href="https://test.domen.com/brands/royal-albert/page/4">4</a>

and it is necessary like this:

2) <a class="page-numbers" href="https://test.domen.com/brands/royal-albert/page/4/">4</a>

On all pages of the store, categories, pagination is formed correctly, as indicated in paragraph 2). In the Uncode theme, I found only one file where pagination is being generated. Didn't find anything with a file search. Where to dig?
Subject purchased. TP writes that the issue is beyond the scope of support conditions.
Thanks for the help.
