Dashboard emails with custom fields show 'Loading...'


I’ve created a report which contains several searches, and subscribed to it for daily emails.

The emails arrive correctly, and show the report, but any fields which are custom fields are presented incorrectly, generally as a static ‘Loading…’ tag, and occasionally text like ‘[1 /]’.

When I look at the HTML source for the email, I see that the fields contain a lot of code to make them editable, possibly also late-loading values into them, e.g. a single element has the following html:

<td class="collection-as-table editable"><form method="POST" action="https://-RT-URL-REMOVED-/Helpers/TicketUpdate?id=80164" class="editor" autocomplete="off">
<input type="hidden" class="hidden" name="Object-RT::Ticket-80164-CustomField-3-Value-Magic" value="1">
<input type="text" name="Object-RT::Ticket-80164-CustomField-3-Value" id="Object-RT::Ticket-80164-CustomField-3-Value" size="15" class="CF-3-Edit form-control" value="62556">
<span class="cancel text-danger far fa-times-circle" data-toggle="tooltip" data-placement="left" data-original-title="Cancel"></span><span class="submit text-success far fa-check-circle" data-toggle="tooltip" data-placement="right" data-original-title="Save"></span><div class="spinner-border spinner-border-sm loading" role="status"><span class="sr-only">Loading...</span></div></form><div class="value"><span><b><a href="https://-RT-URL-REMOVED-/Ticket/Display.html?id=80164">-RT-TICKET-SUBJECT-REMOVED-</a></b></span> <span class="fas fa-pencil-alt edit-icon" data-toggle="tooltip" data-placement="left" data-original-title="Edit"></span></div></td>

Is there any way to just generate simple fields with plain text in them? This simply does not display anything useful in the email.
