When you open the trust menu to do a levelling dungeon from Shadowbringers with the Avatars, the experience it says the characters will receive is translated incorrectly. The dungeon gives different experience depending on whether they are at or below level 80 OR at or above level 81.

In the JP client, this is signified clearly by "~80" and "81~". But in English, the text says "Below Lv. 80" for the first category and "Above Lv. 81" for the second category. This wording excludes levels 80 and 81 so it is unclear which experience category your avatars would fall under when completing the dungeons.
