I am still having problems with this. The 3 custom fields are not being updated. The csv file consist of 4 fields -
Title, Awdur, Cyhoeddwr and Fflag (I renamed the 3 custom fields back to the Welsh equivalents just to be sure of avoiding clashing with Joomla author etc).
I exported these fields using CSVI Pro (no problem). All titles were exported (9529 records) and the 3 custom fields were blank as expected. I then added the data for the 3 custom fields into the CSV file. For testing purposes I deleted most records leaving 8 records with no peculiarities (accented characters etc).
The test file is shown below

I tried to import this file = preview below
All of the records were skipped i.e. not recognised as existing as shown below.
What am I doing wrong? Debug Log attached.
