Reproduction: I added this as an Ability on the 5e OGL sheet: @{wtype}&{template:simple}{{normal=1}}{{r1=[[{1d20, 0d0+10}kh1+5]]}} (A version of the common implementation for Rogue's Reliable Talent).  I noticed that when the ability is used (the way its activated doesn't seem to matter, I checked 'Show in Macro Bar' and used it from there, or just clicked the die to test-roll), and you mouse over the result, the second line in the black box will say something like  = {(9)+()+10}+5 But, the first '+' really ought to be a comma - printed this way, the result of 15 seems pretty confusing - and for someone less technical trying to confirm that the roll was done correctly/by the rules, making this more confusing is not great. I feel like this is probably a well known issue and I'm just not looking for the right keywords, but - help?
