IOS: Creating DNG Custom Presets will not Apply Effect to Photos

1. Lr Mobile, Version: 7.1.0 8C2E26/68
2. IOS Apple Mobile, Iphone v.15.1
3. When I follow the instructions to create a new preset, I:

- load the DNG image file into LR
- Press the 3 dots in the top corner and select "Create Preset"
- Edit in a name and Preset location, then confirm

The preset is made, but when I go to apply it to any photos, it wont change anything and the image stays and looks exactly the same. No edits are made. However when I press "Copy Settings" and then "Paste Settings" on the DNG img, then apply it to a different one, it works no problem. But having a preset would make things much easier instead of having to do that everytime.

4. Expected result: To create a preset that changes the look of an image.
    Actual result: Preset is created, however does not change the look of an image.
