Please compare those two descriptions.
(another project of the same creator)
These tiles are originally arranged in 24 x 24 pixel grid and work well in
Tiled Map Editor. This pack also includes version formatted to use in RPGMaker MV.
(The one you complain about)
It includes a 24 x 24px tileset, a cliff, 3 types of tress and animated waterfall.
This pack also includes a sample map made using Rpg Maker MV
It seems clear to me, what you complain about is not true. The asset was not advertised as ready to use for rpgmaker mv. And since there was a map made with those tiles in rpg maker mv, it stands to reason that those tiles can still be used in that app, despite not being formatted to used there.
You just do not know how, yet. Maybe put your expert photoshop skills aside for a moment and read some guides for rpg maker mv, how to use pixel art that was not custom built for rmmv. It sounds to me, that you to not see the forest for the trees.
