The bug
When you use /fill to put a lot of sponges, some sponges that are not in contact with water will get wet.

Yes, they're in the water. If you look closely at the provided screenshot, the water is over the sides of the sponge platform.
This issue is invalid.
The sponge “layer” is two blocks high
I did /fill ~ ~ ~ ~10 ~1 ~10 minecraft:sponge
Which makes it 2 blocks high
Dana Babaei, the screenshot shows your sponge "layer" on the surface of the water.
Looks like they're getting wet from being connected to the water before all sponges have been placed.
