Multiple relations of the same model seems not supported

class VwUiPosting(models.Model):
    posting_id = models.BigIntegerField(primary_key=True)
    posting_currency = models.ForeignKey(Currency, models.DO_NOTHING, blank=True, null=True, related_name='backend_posting_vw_ui_posting_currency')
    fee_currency = models.ForeignKey(Currency, models.DO_NOTHING, blank=True, null=True, related_name='backend_posting_vw_ui_fee_currency')

class VwUiPostingAdmin(ModelAdmin):
    actions = [csvexport]
    csvexport_export_fields = [
        'posting_id',
        'posting_currency.currency_code',
        'fee_currency.currency_code',
    ]
    csvexport_selected_fields = [
        'posting_id',
        'posting_currency.currency_code',
        'fee_currency.currency_code',
    ]

Field 'fee_currency.currency_code' appears two times in the resulting csv.

Hi @danaki . Thanks a lot for your contribution. Actually I can't reproduce the error you described. I've build a test that sould cover the issue as I understood it and pushed it into the branch issue6. But it just passes fine.

Could you please clarify the misbehavior that you are observing. And would it be able for you to overwork the my test case so that it actually cover your issue?

@thomst hi! I have the same issue. Your issue6's test model is not representing the same model descripted by @danaki where "posting_currency" and "fee_currency" are foreing keys of the same model.
