MInecraft key combination SHIFT double click does not work, why?

Hello if I try to pack a lot of stacks of the same item from the inv into the chest very quickly or the other way around then it doesn't work. It goes there very quickly but bugs back again. I understand that someone can help

Is that with tweak inventory? On-line? Which version?

Do you play on a server If so, this is due to the server's anti-cheat system to prevent hackers from taking advantage of this to duplicate items.

Yes that's on Hypixel

Yes on Hypixel, as he said, this is not allowed by the Anticheat system

Ah so stupid, but thanks +
