When u have the Sticky Header enabled most of a time the sticky head have bugs as the image attached.
Yes, quite a common occurrence currently. The sticky header does not just show the header from the top but also sometimes display the header from the bottom, as a preview of sorts? It needs to just stick to header from the top as you scroll down.
This has been documented here : Sticky headers is buggy · Issue #49 · remnoteio/remnote-issues · GitHub. Will bump it up as it has been around for long. Thanks for the report.
