THANK YOU! I couldn’t work out why it wasn’t working before. The reason was that I put placement to “bottom left” but then I would adjust the placement manually to get it to sit where I wanted, but that would change the setting to “free flow” which would eliminate the “left” property.
So, I will do as you said and use the “bottom left” placement setting, and later move the text to where I want it with the pan/crop function instead.
Thank you for your help!
