This is a known issue with the review UI. The “Keep All” button sometimes doesn’t work, and files can get stuck after a commit. The team is already tracking it.
Please try these workarounds:
Make a small new change in any file, then stage and commit. This can sometimes “wake up” the “Keep All” button.
Rename the affected file, fully close Cursor, reopen it, then rename the file back to the original name.
In the affected file, delete the highlighted blocks, save, then immediately Undo Ctrl+Z.
Press Ctrl+Shift+P → Developer: Reload Window.
If none of that helps, please share the Request ID from the last Agent action (chat context menu → Copy Request ID) and I’ll pass it to the engineers.
