Un-wanted Enlargement of Text
In Pages v6.3.1 (5249), I Copy a line of text. I Paste it just-below. But this text Enlarges from 14-point to 24-point. [So I must change it back.]
Trivial once, but this happens Often. < Boo! >
What can I do, please? What causes this Obnoxious enlarging, anyway? Thank you.
