I wonder if the preset function actually works. From Segments, I choose "Upload Contacts", select my preset (one I saved from a recent process), and "Click the cloud to upload a file". The next screen shows a preview of my data, and the following the mapping. The mapping looks all good, i.e. every field from my upload file matches Eloqua fields. When I finish the process, my Data Import always stays empty. The contact upload notification also indicates there was nothing imported:
If I use the exact same upload file without a preset and map the fields manually the imports works fine. Am I doing something wrong?
