Aksha persuasion seems to always be at disadvantage even when character had advantage on the check.

In the conversation with Aksha, my Paladin had popped a divine channeling to get advantage on persuasion and intimidate rolls. If I passed insight, the success percentage display clearly showed that having this up improved the success chance significantly. But every time the persuade actually rolled, the game rolled at disadvantage, making actual success nearly impossible. At worst, I should have had a straight d20 roll.
