Elements upgrade dross

I've just upgraded to Elements 2019 on my Mac OSX Mojave from Elements 14, largely because of Apple's move fully to support only 64 bit apps in future. My Mac system report now highlights a lot of references to Adobe files left behind after the upgrade which are old 32 bit files which are incompatible with 64 bit. It looks to me as though they are probably redundant but before deleting them I'd be glad of advice as to whether it's safe to do so. I've got a Word file of them all but not sure if I can attach that to this post.
