When you use /locate or /locatebiome, it always shows the x and z positions of a structure, but never the y position. This is important for certain structures, mainly ones that generate underground.

this is intended behavior. How high it is generated is based on terrain (indirectly via world seed), not directly by world seed.
Now that 3D biomes are a thing in 21w37a, this can lead to a number of issues where locating cave biomes might not send you to the nearby one (or even, fail to locate it) depending on your y-position.
And due to MC-236619, the command can send you to "floating" biomes that don't correspond to the surface.
This has been around since /locate was added, as well.
