Open up your fallenswordhelper.user.js file and go to line 4767
You should see the following
Helper.inventory.items = Helper.inventory.items.filter(function(e) {return e.type==12;});//type=plants
Either delete it, or replace it with the following:
//Helper.inventory.items = Helper.inventory.items.filter(function(e) {return e.type==12;});//type=plants
Notice the leading //, that is commenting out the line which is essentially deleting it (but you get to keep it if you want to put it back the way it was.
Restart your browser.
