Hey @pamadesign,
I created a test page and added a Text element with 2 Columns enabled and there’s no display issue (see URL in the secure note). This means there is no issue with the Text Column feature.
It could be that there is a broken HTML within your content. To test that, you can duplicate your page or save your page as a template and load the template in a test page and delete all sections one by one.
If the issue persists with only the Text element remaining, the broken HTML is probably in the Text element itself. Please check the HTML within the Text element. Make sure there is no syntax error. You can use online HTML checker like this https://htmlhint-playground.netlify.app/ to help you find errors.
Thanks.
