You are relatively free in the configuration of your reviewing process. Pay attention to setting the dates and selecting the options you’d like.
The answers in your reviewing criteria may need effects. They should be set to profit from the full range of reviewing functions the software offers you.
There are three entries which are important in the final review: Form of presentation, paper topics, final decision.
The last entry is defined by the rule type Classification. There must only be one entry with this rule type, because it defines what happens to the contributions after the reviewing. If there are two Classification entries, is it configured incorrectly.
If there are two such entries which are answered differently (e.g. once accepted, once rejected), it is unclear what happens with the contribution. That is why you should never have two entries with the rule type Classification in your paper review.
