Unless you have some sort of very weird glitch the level decreasing should never happen. What does happen however is that at the higher levels the amount of XP required to level up is so high that even farming a high XP treat doesn't noticeably raise it, at levels 27-29 the only things that always raise the XP bar are winning the silver/gold trophies in the colosseum, to get a noticeable increase from treats requires you to farm a lot of the high xp treats like peppers/squash/beanstalk.
