The bug
The problem that blocks remain depending on the order of updating blocks of the fill command.
(Old name: /fill lava bug
Old description: When replacing water, lava and obsidian with lava with /fill, not all can be replaced.
I checked this bug in 1.12.2 and 1.17.1.)
How to reproduce
Create a space of 2 by 2 or more(Height is 1 or more)
Fill the space with lava (r1.png)
Put a block of water in the lava (r2.png)
Replace all with lava with /fill (r3.png, r4.png)

Seems similar to MC-187732. Would this happen to describe your issue?

I expected what was going on.
I think the fill command places blocks and updates surrounding blocks in order from the north and east corners.

Obsidian is placed north and east of water.
Lava is placed south and west of the water.
