The nintendo switch version of grounded keeps bugging out and currently the save only works offline

For me the game only loads my actual save while offline, anytime im online t puts me to a save i dont have from a month ago. i feel like ive tried everything from making hundreds of saves to uninstalling the game. i even went offline and midway through the loading turn on my internet thinking it would work but when i loaded another save nothing changed. if some knows how to fix this please help!!
