Sticky Block not working

[Kaorui]

Hi, I’m having a problem making a block (the right sidebar on the picture) sticky. I’ve set parameter for POSITION to be “sticky”, Top “0”, but the block won’t stick neither in the front end or the builder view.
I’ve tried with other pages of the same site, all of them seem to have the same problem. non of the sticky position seem to be working.

Anyone have an idea what the problem could be?

thats wrong setup

add another block inside that block and add sticky to that child block.

Oh, I see. That worked!
Such a simple mistake.

Thank you very much!
