If you can reproduce this, we'd want to see a Debug ID (different from a Report ID) for it occurring. Otherwise, if it's working now, don't worry about it.

Because they're fundamentally different processes. A Report ID includes a list of all errors that have occurred since Zotero startup. A Debug ID includes much more voluminous output generated over a specific period of time, during which you would perform a certain action. For performance reasons, that output can't be left on all the time. Often a Report ID is enough to identify a problem, but when the errors don't provide enough context (such as specific line numbers), we need a Debug ID that covers it actually occurring.
