Disregard this post… modified the old page and deleted the new (faulty one) and all is well.
Pro 2.5.5 - In a “Testimonials” section the row is 1/2 + 1/2. The second column of elements displays in the editor, but disappears on the live page.
If I change the row to 1/3/ + 1/3 + 1/3 the two columns display (live) with the last column empty as you’d expect on the right end. I transferred the contents (cut & pasted) from the old (info) page where this disappearing is not happening.
Pages concerned:
https://transconnex.net/info/ (the old page)
https://transconnex.net/about-fred/ (the new, problem page)
What could be causing this?
