I have created an elementor group skin, but when outputted into my template, it repeats the first line of the array in the number of repeatable sections there are (So if there are 5 values, then it repeats the first value 5 times).
I tried to redo it, but still the same error. The saved data is correct, just the output which is problematic.
Can you please share some screenshots of the subfield value and how it displays with Elementor? Only this skin has the problem so I think there should be an issue with the field or value saved to the database. You can try to delete the field group, skin and recreate them to recheck the issue.
