showing multiple brands for product bundle

Hi, have added this plugin and it seems to do everything I need except for one problem –
when used on a product that is a bundle, and therefore has TWO BRANDS selected, there is no gap between the brands on product page.
So, “Brand_A” bundled with “Brand_B” displays as “Brand_ABrand_B” on the product page, instead of “Brand_A Brand_B” – or, even better would be they display under each other, but side-by-side with a gap is fine.
Site has minimal additional ccs to help with mobile display, shown below details. The problem present on all screen sizes.

Thanks
