How to remove a custom operator block that shows up when I export my project

I don't know why it's happening and honestly i don't want to export my code to a completely new project.

The only way to do this, is by deleting the block before exporting the project.

The thing is the block doesn't even show itself on the bottom right of the sidebar and I can't find it in my custom blocks.


This is what i'm trying to remove

It's a helper for the words/sentences library, which means that it's only used in blocks that are in the words/sentences library. If you used that library, then you shouldn't remove this block, because other blocks use it.

so do i have to export my project to another library?
