Sidebar not aligning properly?

Hi,

I am trying to display different blog posts in different sidebar on different pages. I find that whenever I add sidebars via the “Custom Sidebars” add-on, they tend to display and align differently than my standard sidebar.

This is how I want my sidebar to display (the standard wordpress sidebar – no add-on!):
https://onlinepsykologene.no/category/fagblogg/

However, when displaying throuh “Custom sidebars” they end up like this:
https://onlinepsykologene.no/kompetanse/depresjon/

As you can see, the two sidebars are displaying in different ways. I would greatly appreciate any feedback on how I can make the latter appear like the former.

Best regards,
kyrredyr
