Unable to copy and paste preset settings

I have recently downloaded the Lightroom app on my iPhone as well as the FLTR light room presets app. I was successful in copying and pasting the free presets onto my own photos. This has since stopped working and the option within the three dots on the top right hand ride to "copy settings" or "paste settings" has disappeared. I have also just signed up to the free trial with the intention of paying the monthly subscription and it's still not working. Example attached... Any ideas?
