The bug mentioned on my ticket with the title 'J3 bug econa custom field?' is not only present on Joomla 3. This also happens on Joomla 4. The development version of JCE solves this issue also on Joomla 4. And the next release of Econa will also have a fix for this.
Just wanted to let you know that this is not just a Joomla 3 issue.
