Hi Joey,
Please post to User Voice where the engineers will see it. I think this is a bug since I cannot reproduce it, although I tried. And post the link back here so I can vote on it.

Hello Jane-e,
Thank you for your reply. It goes to show that a well visited forum can have true benefits.
I'm pleased to say that since the last update of Adobe Reader on my iPad Pro, the problem has been resolved.
The cause however is, till this day, unknown. Still,no use in pondering on things that have been resolved.
Thanks Jane-e.
Joey
