When I tested a show type column with category text , I could include several paragraphs totaling around 4400 characters with spaces in one column. I placed the text in “content” box.
However as a practice if one can place so long text in many fields, other community members may have some experiences to share.
You are welcome. Whenever you have special characters in text, please use double quotes around entire text to denote it is text. In your case , the text was breaking at a comma. Such special characters have different usages in expressions etc. , so errors will show.
