1.14.4 to 1.15.1 the Nether keeps resetting

When we go into the nether portal to go into the nether the portal doesn't create itself in the nether. When I recreate a nether from INSIDE the nether I end up in some other part of the world.

I tried destroying my portal, moving the location and then recreating it but I seem to always go right back to the same spot in the nether and there still isn't a Nether portal to go back even after I created on IN the nether itself.

So I feel that the nether is resetting itself or not saving the progress.  For now we'll stay out of the Nether until we can get this fixed. Thanks!
