Multiplayer Server in Palworld Trainer not working when trying to dupe items

[hard kite]

Hello, I just upgraded to pro status, and I am trying to get more technology points. However, when I give myself more technology points, it lets me learn new items but when I close it, it resets the items and my technology points. I have also tried duping items and it is not working, I am an admin on my server, is there a fix to this, please?

I bought my game on Steam
