There are missing points in the consecutive numbers in the list of open points (LOP)!

One possibility is that the irrelevant nodes have been hidden. This also hides all OPs that are assigned to a node that has been set to irrelevant.

Under the “View” tab, the “Hide irrelevant nodes” option should be activated. Uncheck this option by clicking on it again – now all nodes and thus all open points are displayed again.
