Inconsistent volume for new music in sounds.json

Two of the songs added in the Caves & Cliffs update, "Floating Dream" and "An Ordinary Day" use inconsistent volumes when referenced by music.* sound events in sounds.json.

For "Floating Dream", the track uses a volume of 0.4 in all events except for music.overworld.lush_caves, where it is undefined and defaults to 1.0.
For "An Ordinary Day", the track uses the default volume of 1.0 in all events except for music.overworld.snowy_slopes, where it is set to 0.4.

The sounds.json for 1.20.1 can be found as .minecraft/assets/objects/40/40a4222b7ada165fa98cb9215129aeb8d9b6b379, as per https://piston-meta.mojang.com/v1/packages/0e20dc78553f6850535c579b751f5758d0969a39/5.json
EDIT: The sounds.json for 1.20.2/23w40a can be found as .minecraft/assets/objects/2d/2dac7fbd9d8e02e93506635a77182bcaeada6ceb, as per https://piston-meta.mojang.com/v1/packages/682d40601076a696477736377a2ed4677722d6a2/8.json

In sounds.json, notice how the definition for music.overworld.lush_caves uses music/game/floating_dream with no specified volume, whereas music.game, music.overworld.forest, music.overworld.jagged_peaks, and music.overworld.old_growth_taiga all use it with a volume of 0.4. Similarly, music.overworld.snowy_slopes uses music/game/an_ordinary_day with a volume of 0.4, but music.overworld.dripstone_caves and music.overworld.lush_caves use it with no specified volume.

I would expect that the correct configuration is for music/game/floating_dream and music/game/an_ordinary_day to both have a volume of 0.4 in all of their usages, as that would match the configuration for the rest of the songs added in the Caves & Cliffs update.
