👍 bro, that's what I had done in the meantime, guess there's no way around it...

Thanks for the help!

Yes, that is expected, since AFAIK Django only allows one custom template to be declared per ModelAdmin. What I suggest you to do is merge both django-advanced-filter's custom change_list template and django-import-export's custom change_list template into your own custom template and declare it in your ModelAdmin class; or, if you intend to do this in multiple classes, a mixin like this can work:

class CommonAdminMixin(ImportExportMixin, AdminAdvancedFiltersMixin):
    """
    Set a custom ``change_list_template`  to enable both `django-import-export`_ and
    `django-advanced-filters`_ functionality in the ``change_list`` admin view.
    """
    #: template for change_list view
    change_list_template = 'admin/change_list_common.html'

Unfortunately I don't know of any clean way to merge templates, you probably can just copy paste the content of import-export into advanced-filters and save in your template folder.
