Gnomes not staying in place and dropping constant seed packets

I installed Enchanted By Nature and ever since my gnomes will not stay in place. They have not been brought to life with fairy dust. Every minute or so they will move around from the places I put them in the garden and will drop endless amounts of seed packets, upgrade parts and oversized crop seeds. Is this part of the pack and something I cannot reverse now or is it a glitch? I have not enchanted any of the gnomes or brought them to life. I have had to delete all decorative gnomes from my lot because it was becoming too irritating. I play on Mac and have about 90% of all packs apart from a few stuff packs and kits and I do not have one or two main packs.
