You can try another browser (Firefox if you are using Chrome, or vice versa) to see if you can open that control and change it. If it happens in both browsers, there is a manual workaround. It's kludgy, but you can add the field in the Attributes & Abilities tab and edit it there. Under Attributes , click the + Add button. Add a new attribute named default_ro and set its Current value to 0 (zero). Add another attribute named ro_default_rolltype and set its Current value to one of the following values: {{showadvroll=1}} {{roll2=[[ 1d20 (Rolls 2d20 - the sheet's default) {{noadvroll=1}} (Rolls 1d20 only) ?{Roll type?|Normal,&#123&#123noadvroll=1&#125&#125|Advantage,&#123&#123rollhasadv=1&#125&#125 &#123&#123roll2=[[1d20|Disadvantage,&#123&#123rollhasdisadv=1&#125&#125 &#123&#123roll2=[[1d20} (Prompts for Advantage/Disadvantage) {{rollhasadv=1}} {{roll2=[[ 1d20 (Always roll with Advantage) {{rollhasdisadv=1}} {{roll2=[[ 1d20 (Always roll with Disadvantage) Hope this helps!
