The campaign that you are operating on has atleast 30 or more than 30 workflows in it.
When a threshold of 30 workflow is reached campaign's view of workflow switches to this mode. It has been done by design to reduce consumption of information flowing between server and console.
As you might be aware, object in Campaign are based on XML. When hit save button on Campaign the Entire XML (comprised of operation information and of all those 30 workflows flow back and forth). This feature results in reduced usage of memory.
A quick recommendation here is to check do you really need so many workflows inside a campaign. Try breaking them to a new Campaign and you will find it easier.
