Hi James,
That is strange and not possible at all. I’m not sure if we can do a live session considering the random time I work.
Can you please confirm if the correct shortcode is modified and or correct shortcode is expected to be changed in the posts?
May be there is some misread between the shortcode’s “display name” and the “shortcode name”.
If you can share any screenshots, I can identify the problem easily.
Thanks,
Aakash
