Arrows showing up when I use sky mask and some specific presets

I'm using mobile on my IPad Air 11" (M2) with IOS 18.2.1 and my iPhone 16 Pro. I have Lightroom mobile version 10.1.1. When I try to use the sky mask I get two arrows on my photo and it also happens when I use some purchased presets. It doesn't happen with community presets. It seems fairly stable on desktop but it has happened a few times. The fault is intermittent but it is there 80-90% of the time. I have deleted and reinstalled my LR mobile app with no change. It happens with previously edited photos as well as unedited. When I try to use the foreground preset it creates a vertical divide as well as the arrows. 

Hopefully someone can lead me in the right direction. Of course many have tried throughout my life with little success.
