Metatrader open demo account problem.

 

Whilst there are three options when attempting to open a Metatrader demo account it is not possible to select the first or second.

Is the system broken?

 
Select Metatrader broker (the broker which support MT4 or MT5) and open the demo account according to the broker's condition.

For example, I have many demo account with many brokers (for MT4 and MT5).
But I do not open the demo account with MetaQuotes-Demo server because this MetaQuotes-Demo server is used to update MT5 to new beta build and to test beta builds of MT5 (but I am nto beta tester).
So, it is recommended to select the broker(s) for any demo account.
