Layout Problems with WP Store Locator

Hello, we are using WP store locator in our webpage. The store listing contains a few errors. Almost all of the store information is linked to the store’s website. In addition, the address (street and house number) is written without separators in one line with the postal code and the city (see graphic).
I already contacted the support of Store Locator. They say that the theme I use changes the HTML in my store listing. It is a bit different from the HTML that comes out of the plugin right out of the box. For example the link to the store spanning multiple lines is something that my template is doing.
Could you please check that?
Regards
