Fan processed item cannot be process again *after other processing*

[MoePus]

Description

With https://www.curseforge.com/minecraft/mc-mods/create-molten-metals mod
Use the spout to fill molten iron into the ingot mold
The ingot mold and iron ingot can be obtained by blasting washing with a fan.
However, the ingot mold filled by the spout cannot be washed again unless I pick it up and put it back on the belt, or restart the game.

the mold cannot be washed again

I think it should be able to process again by the fan if it is processed by other machines.
