Container in component layout won't split into columns when applied

Hi there, i am a long-term wp developer (acf, custom themes, no page builders…) and i’ve decided to give bricks a try. So i’m pretty new to that. :slight_smile:

My question is:
I’ve created a component with dynamic data from ACF.
Now I wanted to insert a 50% / 50% column into the component layout – but it won’t do anything at this point so the container isn’t split into columns. Where is the mistake?

If I add a column layout to a template, it works as usual.

Any ideas on that?
Thanks!
