villager gat-farming

I do not know what this is or if it is a bug.  On my chat it has "Villager style Gat-Farming enabled."  Then it shows "Gat-Farming function deactivated."  I have not gone to any villages yet in this world: and so, their chunks are not rendered.  I do not see anything wrong with the farms that I have.  I just wanted to report it just in case it is a bug and effects something that I do not know about.  I do have data packs running in this world (autofarm-1542737794 and treecapitator-v2-5-1-1551454023) which may account for this.
