Why can I not see the Object name or the SQLtext that was being run?
The PE display and XML file shows "host redacted". So it looks like all of the data which could reveal the object names has been removed. I don't know exactly why or how that can happen. So I'd encourage you to contact Support (it's free) to get a more accurate ruling on what that's about.
Sorry I couldn't be more help,
Sorry that the host_redacted thing threw me off initially; we get a whole lot of query plan uploads here, but very few deadlocks.
