On mobile so sorry for formatting and everything!

Right now im just trying to do something small and make an adhesive farm. So i planted 6 corn and 6 tato for a total of 6 food, and marcy jumped on all of them, so good working as planned so far. Then i plant 6 mutfruit and all of a sudden marcy is only farming a few corn and tato and has jumped on a couple mut fruit but still making 6 food so its alright, but then i have jun doing the leftovers but i cant get him to farm for a total of 6 food, at first it said 12 food but one of my tatos wasnt growing so i replanted everything and now it only says 10 food production and 2 mutt fruit trees arnt being harvested even though i have 2 settlers farming what should be a total of 12 food! Its driving me crazy!
