Hi @KornDev
Looking at your code, I can see that you are searching for all fields each time a new repeater row is appended to the page. To get around this issue, please make use of the ‘$el’ parameter:
acf.get_fields('', $el).each(function(){
If you only want wysiwyg fields, try this:
acf.get_fields({ type : 'wysiwyg'}, $el).each(function(){
