hey!
Screenshot 2020-04-30 at 19.08.56.png
the frame top setting is correct
for each page, please copy your text and paste ur text into your standard texteditor
i use sublime text
then copy the text from the texteditor and paste it into the texteditor in the gridder
this way you will have removed all the html,
look at the screenshot, theres all types of html markup in your text that changes the formatting and spacing
good luck
