Broken "You might also like" products display is missing spaces

[kickhat]

Hello, block "You might also like" does not work as I would like. Products display is missing spaces.

Example in modules "viewed product" and "in this category" all good. 

+ back office bug. What is this ":ref:" and does not show images. This is not scary, but i want fix missing space bug.

Anyone know how to fix it?
Thank you!
