Inconsistent grammar when using English (UK) between Rift and Dungeon descriptions

Very minor, but there is a grammar inconsistency between the Rift and Dungeon descriptions when using English (UK). The Dungeon description states ”…Echo Shards, and other loot.” which is the same as the standard English version while the Rift description states ”…Echo Shards and other loot.” (missing a comma) in the English (UK) version.
