Bug: Profile page shows events from other profiles

[stoicamarcus]

Description

When viewing a user's profile in the dashboard, scrolling through their events reveals events that belong to other users/profiles.

Steps to reproduce

1. Go to a profile page (e.g., Profile A)
2. Scroll down through the events list
3. Events from Profile B appear mixed in with Profile A's events

Expected behavior

A profile page should only show events associated with that specific profile.

Actual behavior

Events from unrelated profiles appear under the wrong profile. The affected profiles have:

• Different device IDs (confirmed — not the same device)
• Different users on different devices (working from home, no shared computers)
• Same project (ops)
• Same browser/OS (Chrome 146, Windows 10)
• Same country (Germany), but different cities/IPs

Additional context

We're using the Next.js SDK (@openpanel/nextjs v1.3.0) with a self-hosted proxy route (/api/op using createRouteHandler()). We call identify() with profileId, email, firstName, and lastName after authentication.

Since the deviceId is generated server-side via hash(userAgent + IP + origin + dailySalt), we initially suspected a hash collision, but the deviceIds are different for the affected users. This appears to be a data/query issue on the dashboard or ingestion side.
