Problem with adding drug to inventory

Can anyone be of help please…
I just installed OpenEMR 6.0.0. on Widows 10. I am finding it difficult to add purchased drug information to my inventory. When I click “New” which takes you to where you have to add Lot number, Expiration, transaction, quantity etc ), I get presented with the following blank dialogue box without any update of the inventory with relevant information.

Can any one suggest what more I should do ?
Thank you
