Thanks for the response.
Both of the texts are selected from the same Text Style details: Font: Bree Serif; Font weight: Normal; Italic: Off; Font width: Normal; Font size: 20 pt; Character spacing: 0 ‰; Baseline advance: -12 pt; Character fill: R:124 G:47 B:0; Character outline: none; Align paragraph: Centre; Leading mode: % ideal; Use larger of space before and after; Leading: 100 %; Space before: 10 pt; Space after: 25 pt
However, I got to the bottom of the issue - user error as expected. For some reason I had managed to copy and paste the text box on top of each other !! Duh!!!
