Rune/jewel incineration doesn't count in XP Gained

The leaderboards have an entry for XP Gained, however the one thing that doesn't increase it despite giving XP is incinerating runes in /occultist. In the attached video you can see me comparing my XP Gained leaderboard entry before and after incinerating a freshly-purchased Celestial rune in /occultist (400 EXP earned). Notice how the XP Gained stat didn't go up even after a leaderboard refresh (hence why I purchased the rune in the video to increase my XP Spent stat and show the leaderboards have refreshed) and even though the XP bar has gone up shortly after having gone down from purchasing the rune. XP earned from the Dungeon Vault also doesn't increase the XP Gained stat.
