These two race mods conflict?

[xXDeliteXx]

I have these two race mods, True Snow Elves and Vintage Sea Elf
Whenever I load the .ESP for the Sea Elves mod, the option for Snow Elf disappears and my existing character body disappears.
I've tried comparing and cleaning the mod and it seems to not have an effect.
Anyone know why?

Are they both replacing an existing race, or adding new races and all of the vanilla races still exist in game?

 

Do you have a merged patch?

 

Have you tried comparing the two esps in xEdit?

It's been quite a weird experience
Comparing the two files it seems the dude who made the vintage elf mod has used a lot of Snow Elf assets as a base
But somewhere within that the mod is overwriting the other I believe
I've tried changing FormIDs and i've tried renaming editor IDs, but I think i'm missing something
I believe the problem stems from the same area of the mod that allows the mod to be shown in the RaceMenu
but doing the testing that i've been doing I've been unable to find that

I also tried merging but get same initial problem
The merger did show conflicts, though theyre the same conflicts from SSEedit

EDIT: Found a workaround. I saved preset, downloaded new Snow Elf mod, kept the original/ Then I loaded character, showracemenu, changed race to new Snow Elf, then loaded preset.
