buckets only 3ml?

I’ve been trying to get buckets of water to fill a barrel, but I’m not having much luck. If I activate the bucket so I have it in my hands, then I stand in water and right click, I am only getting 3 ml of water in the bucket. Can’t seem to get more. What am I doing wrong?

my bucket just tips water all over me as soon as i try to put any in lol

Hummmm. Anyone else get the bucket to work properly?

worked properly for me (yesterday)
