Problems with drugs/night club

Hey
I am trying to get my drugs into my night club or rave, but when i choose the drug i want, the box that should appear to put the price is missing..
This way i can only choose the drug and click OK, and then it's price will go half of the price sold by the NPCs.
No matter if i use it on the iphone, notebook or computer (using different connections), the problem persists and i can't sell the drugs choosing the prices.

What should i do?

It is for all the players. ..So it's not a problem to you. ..You can not fix you the price.

The last time i played was maaaaaany years ago, and it worked like that

Thanks!
