Can't pick up water/lava in a bucket

I’ve recently made a minecraft server using the recommended spongeforge for 1.12.2 and it seems picking up and placing water/lava with a bucket is broken. It will show the fluid in the bucket but not actually update the source block and upon placement it disappears. Does anybody know a fix?

What mods/plugins you got?

modlist:
Flans
Minecolony
JEI
ICBM-Classic
MouseTweaks

Plugins:
Eagles Factions
Luckperms
TotalEconomy

You probably should have a browse here, if you haven’t already done so:
https://docs.spongepowered.org/stable/en/server/spongineer/incompatible.html

Is it possible something like Minecraft’s native spawn protection is at work here?
Also, can you please tell us what version of SpongeForge you are using?
