Black lines surrounding brush stroke on Photoshop

Hi everyone,

I've searched around google and youtube but can't seem to find a similar issue out there. I was hoping to get your input and to see if anyone else has had the same issue?

I did an illustration piece on Procreate which looked completely fine, opened it on Photoshop on my computer and found out that each brush stroke layer had a black outline around them. This has never happened before!

I've attached a picture for your reference. Please help! Big thank in advance.
