Bug in the JIRA Connector?

[Thomas_crease]

Dear Sir or Madam, 

I've recently been asked to bring in a few more fields to our data warehouse via JIRA's connector, but can't seem to find a couple of fields displayed in the issues - custom fields drop down on the connector page, which we know are definitely there in the back-end. 

We have two fields:

Show - customfield_10869

MOPS Campaign Pillar - customfield_10887

That are not appearing in the checklist for fields that are to be brought through in the next API call, and wondered if anyone has experienced something like this before? 

Any assistance would be greatly appreciated! 

Kind regards,

Tom
