"Header" elements get removed when editing

I have a Looker Studio dashboard with a few pages and at the top, I placed some “report-level” elements like filters and buttons.

This used to work without issues, however, when I now edit my dashboard some elements are removed.
The only option to restore them is to re-add them, or copy-paste them from a previous dashboard.

Is anyone else experiencing this issue?
And what can I do to “undo” this annoying behaviour?

Hello,

You should try clearing your browser’s cache and cookies, and also try accessing your dashboard in incognito mode. Sometimes, Looker Studio updates can lead to misconfigurations, so you might need to redo the report-level elements.
