the screen has blocked where i need to ‘confirm’ when saving a map.

I use an iPhone, when I want to save a route or map, so that it will sync to my garmin, I cannot press confirm as it’s below the screen, when I drag it up so I can see ‘confirm’ in orange, on the right side, if I press it, it does nothing, as I have the screen dragged up- it’s extremely irritating.
