There's a dupe glitch on my server!

Im pretty sure this is only my server, but I want to know how do I fix it. There is a dupe glitch for bp on my server where after you successfully research an item in the research station, you can learn it and it will not go away after you learn it.

hey, I have players saying that it's still there

 

Can some make it sure that players can ONLY learn BP if it's inside their inventory? because for some reason, after researching a BP and learning that BP while it's still inside the CB, it will still there after the item been learn, on my server at least.

 

They can only learn it when get from Research Bench.

 

I'm not talking about researching the bp, im talking once they acquire the bp, they can only learn it if it's in their inv.
