Popular Products strange behaviour

[AdmiralM]

Good day,

I have on homepage the Popular Products module. The website has multiple languages.
On default language(English) the module displays 4 products(on 4 columns) and with the help of the forward-back buttons you can swipe through the rest of the featured products.
On any other language the module displays only 2 products aligned(on 2 columns) and every other product is listed on a new line.
I've checked and removed for every product any text format or special tags but still no change. The only time a slight change is made(are showed 3 products on 3 columns) is if I disable the first product.

Any idea on what is the issue and how to resolve it?

Found the solution as follows:
Any tags <strong> or <span> will break the inline display of the 4 column.
