My structures don't spawn

so hi, i recently updated my MCreator software to continue my mod, everything loads normally, the items, recipes, files, sprites, etc.

Yesterday I made a new structure, saved it and loaded it in the resources part, all good for the moment, but when I try to add it to one of my custom dimensions, it does not load, even when I put it they appear practically all over the map... (It should be noted that I had already done a structure before, and it generated perfectly well, this had never happened to me, until I updated my MCreator to the most recent version)

So anyone who can help me?

important fact: I started the project in version 1.12, then I changed it to 1.14, and finally to 1.16 ... the first time I changed the version it gave me problems, but nothing like this.

And excuse me for bad English, I don't speak that language
