Highs after loop algorithm decreases basal

Hi! The loop algorithm tends to decrease my basal when I’m riding at ideal blood sugars around ~90-110, because I’m assuming it is predicting I’ll go low! After the basal decrease, I end up having high blood sugars. What setting should I look at adjusting first? I realize that I should reach out to my physician, but prefer to make minor tweaks on my own. Thank you!
