Report View problem - display nothing

Hi, i have created a new doctype Project Location, accidentally I have clicked something in the report view and I can’t remember what I have clicked and what happened is no longer displaying any records at all. The list view is fine, it displays all the records but when i click the report view it display nothing. I have tried looking for any available command or button but i can’t find any. What could be the problem? Thanks.

Try it.

Upgrade the version, Migrate the site, and bench build --force.

ohh is this the only solution? It could be more hassle if i upgrade and migrate. But anyway, thanks for your response and suggestion I appreciate it.
