/Locate and Eye Of Enders leading me to nothing

This world was created pre 1.14. I was using eye of enders to locate my stronghold and they led me to a specific area. I dug down where it had stopped and there was no stronghold there. I made a copy of my world and used the /Locate command (because cheats are off on my world) to find my stronghold. It says it successfully found a stronghold at the coordinates 674, (y?), -718. I teleport to that area and its the same place the eye of enders are taking me. I dig down and there is nothing. I then made a new world with the same seed (2096126575, the new world spawns at the same point as my world) and then I use the /Locate command again. It came up with the same coordinates, so I teleport and now there is a village in that location. I dig down and now there is a stronghold there. I know it is probably a problem with the fact that I created it pre 1.14, but I would like to know how I can fix this if possible. The pictures are the before and after of the copy and the new world, with the coordinates in the corner. Thanks.
