Updating metadata with unchanged ISBN

I tried to update the metadata (resource) by resubmitting via the web deposit form but received an error message (see below) saying that the ISBN has already been assigned. I resubmitted without the ISBN and then it worked. How do I update the metadata while keeping the ISBN? When submitting a new edition with the same ISBN but different DOI, there was no such error.

<?xml version="1.0" encoding="UTF-8"?>

<doi_batch_diagnostic status=“completed” sp=“ds5”>
<record_diagnostic status=“Failure” msg_id=“24”>
all doi’s under the current book element
ISBN “9780578949505” has already been assigned, ISBN assigned to other title: Information Display Measurement Standard/9780578949505
