Treasure maps are always the same

I found in total 8 maps on my world and all pointed the same treasure even the one map I found 5000 blocks away

Steps to Reproduce:

1. Find any underwater structure (exept portal)
2. Get the treause map (if there is one) and load it so the "X" appears
3. Repeat the same thing in any sturcure in any ocean as far as you want

Observed Results:
The map always poimts to the same "X"

Expected Results:
The treasure maps should be diferent (ecpecialy if there are found very far away

Screenshots/Videos attached: Yes (The drawn picture swohs where the map was found and where the "X" is marked.)
