Loren S. said: It sounds like you have advantage rolls turned on. This is the default setting on the OGL sheet, to always roll with advantage. If that is the sheet you are using, click the gear icon on you character sheet and you can change your roll settings there. As Loren said: If you're using the Roll20 5E OGL sheet, at default, Advantage/Disadvantage is rolled automatically. If you go to the sheet's settings, you can adjust how you want the dice rolled: Always/Toggle/Query/Never Roll Advantage (see this wiki page for more info: <a href="https://wiki.roll20.net/5th_Edition_OGL_by_Roll20#General_Options" rel="nofollow">https://wiki.roll20.net/5th_Edition_OGL_by_Roll20#General_Options</a> )
