I am guessing you are accidentally keying a keyboard macro.
When I did a Ctrl-R it rotated the image one turn. And, Ctrl-I got the new person entry fields.
You may be hitting the Ctrl key instead of the Shift key.
I love my laptop for the most part, but the Ctrl and Fn keys are placed where they get touched when my hands get lazy, and it changes things on the keyboard responses.
Try doing these two deliberately and see if that is the issue.
Soemwhere in the site here is a list of all these keyboard shortcuts, and if you learn to use them you can speed up your transcriptions. Sorry you had the glitch, but glad you reminded me of these two.
