Top position continually readjusting on some sidebars

[DanyDD]

Hi,

Is there a main reason why this is happening on some pages (this one for example https://danyduchainethemes.com/shade-garden/2019/04/14/how-a-stranger-things-kid-inspired-littles-most-enviable-look/) and not other (this one : https://danyduchainethemes.com/shade-garden/contact/).

On the pages where it readjusts, it makes the sidebar jittery.

Thanks

Both these examples seems to work fine now. Can you please share what was the issue?
