First, use the controls above the map to enter your world seed, Minecraft version and dimension (Overworld, The Nether or The End). You can also use a savegame to import the seed, or use the Random button to find new seeds.

By default, the coastlines for versions 1.18 and above don't match up perfectly. This is not a bug, but rather because the map shows the underlying biomes instead of the exact terrain. Near coasts, ocean and river biomes often have land, while land biomes can be underwater.

Some biomes and features don't exist in every version, and some combinations are extremely rare or can't generate at all. Try fewer conditions and broader biome and feature selections, and make sure each condition is in the right dimension tab. Adjusting the search area can help too, depending on the condition.

Since those structures are small, often buried, and can be offset 10-20 blocks from the chunk center, you might have to do some searching/digging to find them. The y coordinate isn't shown for every feature. For structures that always generate on the surface or seafloor, this shouldn't be an issue.
