Custom playlist cover not centered

I am using the iPad running iOS 10.3.3, and I have made a custom playlist where I want to change the playlist cover, and when I try to do it, the editing process doesn't let me crop the image properly, and instead of showing the full image I chose for the cover, it always cuts out on the top left corner of that image, making it look very ugly. I have restarted the Music app many times, I also restarted my iPad, but none of these things fix the issue. Does anyone have a solution to this? I am soon going to buy an iPhone that supports iOS 13, I hope that this issue is fixed on the Apple's latest OS.
